Delete reminders that keep returning

Last reviewed on May 23, 2014

When reminders just won’t dismiss, there are several things you can try to get rid of it:

Use the Cleanreminders switch. This works most of the time.

When cleanreminders doesn’t work, look for the appointment the reminder belongs to and delete it.

When you can’t find the appointment, you need to use MFCMAPI to browse “inside” the message store and delete the reminders. Outlook will then rebuild the list with just the valid reminders.

Use Cleanreminders switch

The easiest way to try to get rid of corrupt reminders is by closing Outlook and reopening it using the /cleanreminders switch. To do this, press Windows key + R to open the Run dialog. typeUse the cleanreminders switch

outlook /cleanreminders

in the field and press Ok.

Make sure you have a space between Outlook and the slash. Using ‘outlook.exe’ is optional – just the program name should work.

A (very) few people will need to use the full path to outlook.exe. Click Browse and look under C:\Program Files\Microsoft Office\ (C:\Program Files (x86)\Microsoft Office\ if using 64-bit Windows).

Delete the Appointment

Sometimes the cleanreminders switch doesn’t help. When this happens, look for the appointment that is associated with the reminder and delete it. If you can’t find it, you’ll need to use MFCMAPI to delete the reminder.

Use MFCMAPI

Download MFCMAPI

Please note the steps are slightly different when you use a pst file or Exchange mailboxes and may vary slightly with newer versions of MFCMAPI. These instructions were last updated for MFCMAPI v15, March 2012.

PST File (used with POP3 and IMAP accounts)

    Reminders folder in pst file

  1. Run MFCMAPI
  2. Go to Session, Logon
  3. Select your profile
  4. Select your data file where the stuck reminder is. (It may be use your email address as the filename.)
  5. Expand “Root Container”
  6. Right click “Reminders” and select “Open Contents Table”
  7. New Window Launches with Title Reminders
  8. Find the corrupt reminder(s) then right click and select “Delete Message”. Do not select all reminders, as that will delete all appointments.
  9. Close MFCMAPI

Alternately, you can delete the Reminder folder and Outlook will rebuild the valid reminders.

Exchange Mailbox

    Reminders folder in an Exchange mailbox

  1. Run MFCMAPI
  2. Go to Session, Logon
  3. Select your profile
  4. Select your Mailbox
  5. Expand “Root – Mailbox”
  6. Expand “Finders”
  7. Right click “Reminders” and select “Open Contents Table”
  8. New Window Launches with title “Reminders”
  9. Find the corrupt reminder(s) then right click and select “Delete Message”. Do not select all reminders, as that will delete all appointments.
  10. Close MFCMAPI

You may need to log into the mailbox using a non-cached profile and delete the corrupt reminders from the mailbox on the server too.

Delete Outlook Reminders Tutorial

When you are deleting reminders from Exchange accounts, choose your Mailbox name. When you are deleting reminders from POP3 accounts or *.pst files, right click on the pst name that contains the corrupt reminder.

Remember: Delete only the corrupt reminder(s) when you delete from inside the reminder folder you are deleting the appointment too.

If you can’t find the corrupt reminder, you can delete the entire Reminders folder. Outlook will rebuild the folder and the (good) reminders.

This updated tutorial shows how to delete reminders from both local pst files (used with POP3 or IMAP accounts) and Exchange mailboxes, beginning with POP3 accounts. The Exchange mailbox steps begin at approx 55 seconds (about halfway though).

    what if the error occurs in OWA? Synced to an Android phone.

    I assume then that the problem is NOT local, I don't see anything at the Exchange end, and it appears to be just 1 of 12 users..

  2. Chris

    These MFCMAPI instructions caused many calendar items to be deleted, not just the reminders. Is this expected or did I do something wrong? I was in the reminders folder...

  3. Chris

    Yes, many of the calendar items were in the dumpster, even though I selected delete to deleted items folder.

    I did perform this against another users mailbox. Do I need to run mfcmapi locally?

  4. Ryan

    Hi Diane,

    I am running MFC Mapi and running it locally on a non cached mode of Outlook 2003 sp3. I am opening my Mailbox store, expanding root container, going into the reminders window and deleting the reminder, by right clicking and delete message. However when i do this it deletes the entire reoccuring appointment. Do you know why this could be happening? I followed the instructions word for word.

  5. Patrick

    I have ~60 reminders that will not clear. They show up in the Reminders folder for my local profile, but they do not show up in the Reminders folder for my OWA folder. When I try to delete individual reminders or the local Reminders folder or the OWA Reminders folder, I receive an error:

    Error:

    Code: MAPI_E_UNKNOWN_FLAGS == 0x80040106

    Function lpParentFolder->DeleteFolder( lpItemEID->cb, (LPENTRYID) lpItemEID->lpb, lpProgress ? (ULONG_PTR)m_hWnd : NULL, lpProgress, ulFlags)

    File .MsgStoreDlg.cpp

    Line 973

    Any idea how I might solve this (and thereby solve the annoying recurring reminders problem)?

    Thanks!

  6. gkupfer

    I also downloaded the MFCMAPI file to fix an error message " Cannot turn off the remnder. You may be reminded again. Cannot locate recurrence information for this appointment" The outlook /cleanreminders method did not solve the issue.

    I followed the "Delete Outlook Reminders Tutorial" and discovered that the MFCMAPI file that I downloaded is different than in the tutorial. I downloaded ver. 15.0.0.1030. The problem is that this version does not show "mailbox" after choosing "Outlook" as my profile, so I can't even locate the root container that has reminders as a sub-folder.

    I am running W7, 32 bit and wondering if anyone can get me to the reminders in MFCMAPI

  7. steve

    Dianne,
    I am running Outlook 2010 and have a reminder that I have deleted from the Calendar but each time I open Outlook up pops the reminder, which is now 4 weeks overdue. What ever means I use to close it up pops a box saying "Cannot turn off reminder. You may be reminded again. You must enter a positive duration."

    I have used outlook /cleanreminders and have tried using the MFCMAPI as stated above but where you say select your profile, the only profile available is outlook and when that is selected there is no reminders shown in the expanded root container. Where do I go from here? Thank you.

  8. Carolyne

    Hi Diane, I had 2 old recurring reminders that I couldn't delete and kept popping up in my reminders window. I tried using the Cleanreminders switch. Now, I have over 1600 reminders popping up in my reminders window. Very upsetting. I can't delete them because I keep getting an error message that says: "Can not turn off reminder. You may be reminded again. You must specify a valid date and/or time. Check your entries in the dialog box to verify they represent a valid date and/or time."

    I tried using your other suggestion of using the MFCMAPI to delete the reminder. However, when I go to select my mailbox, my only options are 2 different archived folders or a personal folder. Although I've tried each one and gone to the Root Container, I can't find the “Reminders” and select “Open Contents Table”.

    Do I have to reinstall a new version of Outlook? What do you advise?

  9. Brian Matthews

    Diane, you are brilliant! The clean reminders solution worked for me. Your solutions are best laid out and explained on the entire web regaridng this issue. Thank you. Other help pages explain that you can use MFCMAPI, but they don't show you how to us this tricky bit of sofware. Thanks again!

  10. Mark Richards

    First, thanks for the great information. I'm not sure if my issue is a Reminders issue or not. I am on an exchange server using Outlook 2010 and it is synced with my Blackberry. My profile is for the exchange server shows as non-cached. I have recurring meetings on my calendar that were scheduled by coworkers. Over time, those meeting times have changed or been canceled but the meetings still show up on my calendar along with the new meetings. I have tried deleting them from Outlook, I have tried the cleanreminders method and I have tried the MFCMAPI method. I was able to delete the appointments using the MFCMAPI program but a short time later everything is back on the calendar. No matter what I do, the calender appointments keep reappearing. Any ideas how I can delete them and keep them deleted?

  11. Lea Ann Weisbruch

    When I move emails from my inbox in Outlook to personal folders - something generates an odd "flag" - that has a red flag with a person on it - and then it triggers reminders about the email - even after I have handled the email. I can't find anything on line or in Outlook help to make this stop and/or find out why it is even happening.

  12. Cecilia Sepp

    This was utterly useless. Deleting the appointment did not work.

    Neither option for cleaning reminders in a .PST file worked. I tried both "cleanreminders" and downloading BOTH Versions of MFCMAPI. I tried both the 32 bit and the 64 bit.

    None of the drop down menus look like the ones in the screen pulls or the tutorial video. When I select "Session" there is no plain "logon" option -- there are several, none of which show me my accounts.

    I have Outlook 2010, and it is running on Windows 7.
    I checked my settings in Outlook and it is selected as the default mailbox at startup.

    I downloaded the January 2010 version of MFCMAPI which is the link on this page.
    This was total, complete waste of my time. This does now work at all.

  13. Yvonne

    Hi Diane
    Thank you. Thankyou.
    I used the easy to follow instructions for (clean reminders switch) method and it worked!
    The annoying reminder I could not dismiss for 43 weeks did not pop up!
    I will keep a link to find your solutions for any other problems I have.
    Cheers and thanks again!

    Hi Diane,

    I have just recovered an Outlook 200 PST that was corrupt. I have upgraded the client to Outllok 2007 and opened the PST there and copied the contacts into his new PST. None of the email addresses came in and every time I access a contact I get a reminder for each contact that will not clear. When I dismiss all they pop right back up?

  15. Mike Hayes

    Sorry it should read, "recovered an oversized Outlook 2000 PST".

  16. Mike Hayes

    Yes, I have tried that as well as reset folders. As soon as I access the contacts the reminders pop up. I have tried reseting all the flas to "Clear flags" as well. I am about to try the MFCMAPI option. I have never seen this happen?!

  17. Mike Hayes

    Running MFCMAPI, I received the following error:

    Problem array:
    Index: 0x00000000, ulPropTag: Tag: 0x36020003

  18. Pete

    None of these solutions worked for me but I did just notice something interesting about ALL of the Reminders that were coming back for the user I was helping:

    When I opened the offending Appointment tied to the Reminder it states that it has been "Tentatively Accepted." I thought maybe if I officially "Accepted" it I might be able to get rid of the Reminder pop-up. Weirdly, when I tried that (Accepting it), the Reminder would still pop-up, and when I re-opened the Appointment it still said "Tentatively Accepted" albeit it was now timestamped with the current time that I had Accepted it on.

    Maybe this is diagnostic of something? Also some of the reminders have a reminder time of: 1525252321 minutes (I googled this and found some things but very few and none that worked).

    UPDATE: I noticed also that the offending Appointments seemed to be organized/requested by someone else. I wondered if perhaps it was too late to "Accept" since they were all in the past? So this time, as they re-popped up I tried Declining the invite, and then Dismissing the Reminders for them when they popped up again.....holding my breath now to see if they come back.....nope, did not work.....all popping back up again.

    UPDATE #2: I cannot even delete the original Appointments. After awhile they reappear too. This user is synching the Calendar with an Android. Maybe it is re-synching these back on? I did a synch refresh on the Android. Didn't make any difference. This user is using Exchange/Cache Mode. Something, somewhere is confused.

    Can I turn Reminders off completely??

    Arrghg...

  19. Ian Thompson

    Diane,

    You are a genius! I've had a stuck appointment in Outlook for about 3 months. This was preventing my iPhone syncing with Outlook on my PC. All is now well. Many thanks!

  20. Scott Barentsen

    Diane - u rock! I had a pesky, annoying, broken for weeks reminder in a pst data file and you showed me the way. THANK YOU!

  21. Mange

    Thanks very much for this. helped me get rid of those annoying reminders that wouldnt be deleted !

  22. Tracie

    I have a frustrating issue. Running Exchange 2007 sp3. Client Outlook 2007.
    User A had a calendar event where she invited User B. Then User A delete the event but User B declined the event. Now User A gets an email every few minutes that User B declined but it says The meeting is not in the calendar; it may have been moved or deleted.

    I've verified that the event is in neither User's calendar. I've opened outlook with the switch /cleanreminders for both users. I've deleted the reminders folder for User B. So, User B keeps sending the decline but User A says "I don't know what you're talking about"

    Any ideas?

  23. Tracie

    We figured out our issue ... user B declined the appt in the iPad ... it was the iPad that was continuously sending out the message - so we re-created the email profile on it (rebooting and resetting it didn't work) and now it has stopped sending the decline messages.

  24. Brian

    Hello Diane,

    I am in desperate need of your help. I used this tool to clear out reoccurring reminders but I missed the part that said not to select all reminders and now all of my appointments are gone! Is there any way to recover these appointments using this tool

  25. Brian

    This is an Exchange account and it appears that some of the appointments are in the deleted items folder. I'm gonna check and see if we can recover the appointments from a recent backup.

  26. Brian

    OK so after checking some of the items are in the deleted items but not all because this calendar contained years worth of appointments that we would like to have that aren't there. So we have a PST backup of the calendar from a few days ago that we're going to use to recover the items. So question - I should be able to just simply import the PST and merge it with my existing calendar correct or is the process more complicated than that.

  27. AnnaLee

    Hello Diane,
    I'm having an issue with Outlook 2003 reminders. I used MFCMAPI to remove all of the appointments. Once I did this all of my contacts were gone. When I try to enter them back into my contacts the reminders show up again. I tried importing the contacts from a previous backup I made before the persistant reminders issue happened and the reminders still show up. The number of reminders equals the number of contacts I have in my list. I tried turning off reminders through options>advanced and now my cursor constantly shows up as the blue circle like it is busy. Do you have any advise as to what I should try next?

  28. AnnaLee

    In the reminders windows it just shows the contact name and all 65 other contacts I have. When I click on "open item" it shows the contact information. Under Activities-All Items it shows "there are no items to display". Activities-Upcoming tasks/Appointments "there are no items to display" There is no birthday information recorded in the contact's information.
    When I click "Dismiss All" all the appointments go away and then reappear showing as "Follow up" with the present date and time.
    I have not created any appointments in my calendar

  29. Joe Obrien

    I have tried all methods mentioned in this thread and I can't seem to get the reminder to stop popping up.

    * Exchange 2010
    * Not in Cache mode
    * No .pst file
    * All deleted items permanently deleted
    * All mobile devices not connected (e.g., not re-sync'ing)
    * Event was a meeting scheduled by someone else, that I accepted, but subsequently deleted

    Any advice?

    Joe

  30. mike

    Diane, I have this issue and downloaded and ran the MFCMAPI. I used the instructions on removing the reminders that would not delete and it worked. Now the problem is that new reminders we are unable to delete now, so its the same problem again. What do I need to do to prevent this going forward. Is there a reason for this to continue, is the exchange file currupt? Please reply! thanks

  31. Singh

    Delete your profile from your Phones!!! This occured for me and the solution to this problem came out to deleting the profile on my Iphone!

    After this I went back to outlook and held down shift + delete on the meeting and it was solved!!!!

  32. Larry

    I have a user that, each time they receive a meeting request, every reminder they have ever had pops up. I used the outlook /cleanreminders switch and that solved it until the user closed and re-opened Outlook. They have over 6,000 reminders, so trying to find the one that is the issue would probably be impossible. Any suggestions?

  33. Bilson

    Having issues using MFCMAPI, having two errors.

  34. Bilson

    microsoft outlook 2007, seems to be 128bits version

  35. Bilson

    Unfortunately it is not pst file, it is mailbox. I am using win xp. tried to repair the outlook but it didn't work.

  36. Bilson

    managed to delete most of the wrong reminders, but left 1 which is the first one that has problem. it seems that before synchronizing properly, i deleted the calendar event. That the reminder is sort of having problem.

  37. Louis

    Thank you for your help. I eventually had to use mfcmap which is not very intuitive and the instructions on how to navigate to the Reminders box were not straight forward, but after some experimenting and your helpful instructions I eventually found and deleted the offending reminders.
    I am not a computer expert and I found all the extra unintelligible columns rather daunting, but after perseverance it's great to get rid of the annoying reminders.
    Thanks again.

  38. Bilson

    No idea what happened.
    Opened outlook yesterday, the reminder went haywired again, popping a few reminders of past 2 weeks. Just dismissed all of them.
    After synchronization or update of outlook, all the issues were resolved.
    No more old reminders, no more task menu issues, no more unreceived emails. All my emails that were not received by outlook inbox for the past weeks appeared.

  39. Ed Starke

    Hi Diane, I'm not receiving reminders in Outlook mail from Outlook Calendar.

    I used to receive the reminders but it just stopped. I haven't changed any of my settings at all.

    I already have calendarnotification@email.microsoft.com in my safe sender list.

    I appreciate any help you can provide.

    Thank You

  40. Ed Starke

    I followed your instructions and issue wasn't solved. Any suggestions? I'm figuring the problem is on their end because it seems strange that all of a sudden I'm no longer receiving my calendar reminders to my hotmail email address.

    I'm running Windows 8 and I just go into the calendar that's in metro add an event for a specific day and time, set the reminder, and then I'm emailed a reminder beforehand the day of the event. That's how it was working until 6/12/13.

    I've checked my computer and it's in good working order, fully updated, and no one uses it but me.

    Any guidance would be greatly appreciated.

    Thanks

  41. Ed Starke

    Followed your instructions and problem remains. What else should I do?

  42. Mike Nostrom

    Hi Diane,
    I have one user who is having to dismiss reminders twice. They are running Windows 7 64-bit, Outlook 32-bit and Google Apps Sync to sync Outlook with Gmail. I just setup this person's new computer and then Google just pushed out a new update to Google Apps Sync as well. I have run the /cleanreminders switch on their Outlook several times. This allows them to successfully dismiss a few reminders but then other reminders will re-appear.
    Any thoughts?

  43. jakcie

    Thanks a lot, I appreciate your very quick response

  44. Brian

    Thank you so much for the info. :)

  45. Andi

    As soon as I open up Reminders I receive the following error message:
    Error:
    Code: MAPI_E_NOT_ENOUGH_MEMORY == 0x8007000E
    Function lpContentsTable->GetRowCount( NULL, &ulTotal)
    File ContentsTableListCtrl.cpp
    Line 647

    I can click OK but then I don't see any reminders; although there is still a reminder in Outlook that pop ups for an event that was deleted!

    Do you know how to resolve this?

  46. Andi

    We ended up having to fail over our email cluster and this error message disappeared along with the ghost reminder.
    Thank you anyway for your help.

  47. Jon A

    Hi Diane

    I'm using MFC MAPI on a Vista PC on a pst file using POP. When trying to delete reminders I get three options: "Delete to deleted items", "Permanent deletion (deletes to deleted item retention if supported)", and "Permanent delete passing DELETE_HARD_DELETE (unrecoverable)."

    Choosing the first two does nothing - the reminders are still there. When I choose the last I get the message:

    Error:
    Code: MAPI_E_UNKNOWN_FLAGS == 0x80040106
    Function ((LPMAPIFOLDER) m_lpContainer)->DeleteMessages( lpEIDs, lpProgress ? (ULONG_PTR)m_hWnd : NULL, lpProgress, ulFlag)
    File FolderDlg.cpp
    Line 691

    What am I doing wrong?

    Thanks for your help
    Jon

  48. Nivine

    Hi Diane,

    I tried both solutions, the /cleanreminders switch did not resolve my problem and when I run MFCMAPI i can't find “Reminders” in "Finders" when I expand “Root Container”
    i'm using outlook 2010 and OWA exchange server.
    Hope you can help me.

  49. Djo

    Hello Diane, I found something.

    Using two Windows 8.1 computers with Outlook 2013 (syncing outlook.com account) the past reminders of completed tasks kept popping up. I have tried the MFCMAPI and the /cleanreminders approach but these reminders kept popping up. With the MFCMAPI approach the problem was that I received an error: I could not delete the reminder.

    However, I encountered something that hopefully can avoid any further frustrations and maybe you can create a less intensive approach with it.

    I noticed that a reminder of a task has a on/off checkbox, a date field and a time field. Pressing [Delete all] on the reminder windows seemed to uncheck the checkbox, but it did not clear the field of the reminder date and time.

    ** Manually deleting the reminder date and time field (so it says "None") and then saving the task proved effective. The reminder was not bounced between devices anymore. **

    Could you maybe extend this now to a more practical solution?
    Have you any idea how to edit multiple task at the same time? Or do you have any other suggestions or relating information about why this is happening in outlook 2013?

  50. BPackard

    I have tried all these solutions. I have had limited success.
    I have looked around and have yet to find info on this:
    How do I determine which reminders are corrupt in the MFCMAPI tool?
    There is quite a bit of data and I cannot see a way to distinguish the good from the bad.
    I have tried deleting the entire (non cached) reminders folder, no luck there. /cleanreminders doesn't seem to help. I have also deleted the entire Outlook profile and reloaded. After Outlook pulls down the mail items, the reminders issue comes back. This is happening for multiple users in the AD environment. Is it possible the corrupt files are being pulled down from Exchange?

    Exchange Server 2013
    Outlook 2010 and 2013 (Happens on both client versions)

  51. BPackard

    Yes, the same number of reminders showing in the reminders folder is also showing in the one window. I would guess the same applies for the number of reoccurring meetings and the ones shown in the reminders folder.

    After removing ALL of the reminders via MFCMAPI tool then reloading the profile, the problem seemed to be fixed. Later, the problem came back. It seems the data stored in Exchange contains the corrupt settings/items and the issue comes back after the sync is completed.

    I have exported the exchange mailbox to a PST. I have also scanned this PST for errors, some were found. Perhaps completely removing the user's mailbox, create a new one, then import the repaired PST into the recreated mailbox would do the trick? Seems drastic, yes.

  52. BPackard

    Moderate success!!!

    Ok, the issue of 20-30 reminders popping up in one window seems to be fixed.

    What I did:
    1. Backed up/exported the PST from Exchange Server
    2. Logged in as the user and exported just the calendar.
    3. In non-cached mode, deleted EVERY calendar entry via MFCMAPI
    4. Scanned and cleaned the user's OST and the exported calendar PST (SCANPST)
    5. Reopened Outlook to verify there were no rouge calendar entries.
    6. Once I was sure it was clean, I imported the newly cleaned calendar back into the users mailbox via EAC.
    7. Reopened the user's outlook, issue fixed.

    Now the issue of two reminder windows popping up for one event. (Have to hit dismiss twice for two different reminder windows).

    I read that this is a sync issue with mobile devices, correct?
    This is happening to both Android and iPhone/iPad users.
    Any info on this would be very helpful.

  53. BPackard

    Right, two reminder windows. Yes, iCloud is in play. I suspected the same, I had one of the users log into iCloud and remove calendar entries. No word yet. Is it possible two-way sync is pushing back to Outlook? Would this be as simple as setting the iphone to sync from Exchange to device only (One-way)? Grrr....so close on this, I can taste the closing of these support tickets. :)

  54. BPackard

    Diane,

    After more research, I have discovered the second reminder window popping up after hitting dismiss all is not isolated to just Apple products. This is happening with Microsoft Surface, and Android devices as well. I have checked Outlook clients for "sync" add-ins such as iCloud and none were found. When the user leaves for lunch I will log in and test Outlook in safe mode, but not optimistic. Since this is happening to multiple users with disparate mobile devices, I am leaning to the root cause being either on the Exchange server or Outlook client. Could there be anything else (besides mobile devices) causing a second reminder window (same event) to pop up immediately after hitting dismiss?

  55. BPackard

    Diane,

    I believe I have fixed both issues. Thank you for your help.
    The steps I detailed above worked. The only thing I did not do was re-enable cached mode.
    Once I enabled cached mode on the user's Outlook client the issue of 2 reminder windows opening back to back went away. This was tested on multiple users, all were successful. I will gleefully close the support tickets on this today. Well, maybe tomorrow...just to be safe. Thanks again!

  56. Leo

    Legend! That's been annoying me for months. Thank you

  57. Charlie Mann

    I recently switched email hosts to Outlook 365. I exported the pst file and then deleted the old email account from outlook. I then created a new email account in Outlook and connected it to 365 and then imported the saved pst file. This created some duplicate calendar entries, which I fixed, but I am now getting 5 reminders from the Outlook calendar entries, even after deleting the calendar entry. I tried the cleanreminders which didn't work. I opened the MFCMAPI but the instructions didn't match what I was seeing. Any suggestions?

  58. Steve Battiato

    Outlook 2007 on Windows 7. Google Apps for Business with Google Sync. Five reminders continue to pop-up. Tried Outlook triggers: cleanreminders, etc. Tried MFCMAPI and ScanPST. ScanPST finds no errors. Trying to modify any of the appointments fails to save. No specific errors. Any help is appreciated.

    My I-Phone 4 was re-insterting the appointment on my calendar. After I deleted it with MFCMapi.exe, it kept coming back, outlook /cleanreminders did not work, it came back. Using MFCMapi.exe to delete the reminders folder did not work, it came back, AND it was popping up 1-2 times a second. Finally I clicked on Calendar in my I-Phone 4, went back to the date of the appointment, and declined it. Instantly it stopped re-appearing/deleting , re-appearing/deleting, and constantly popping up every second in my outlook 2007 Windows Vista client.

    Thanks for the suggestion, but that didn't work either. I was able to figure out the MFCMAPI and deleted all the reminders and everything is working well now. Thanks again for the help!

    Outlook 2007 on Vista. Cleanreminders didn't work. I'm not technically strong but I watched your video and tried MFCmapi, which cleared the reminder. As a note, "Outlook" was the only profile name I saw so I simply followed the remaining sequence of steps you described for Pop 3. Thank you.

    Hi Diane - I am having a slightly different problem. Win 7, Outlook 2010, Apple icloud sync to a phone and ipad. Not using Exchange, just local .pst Only on the win 7 system, some reminders cannot be dismissed nor snoozed. They come right back up after trying. They are current appointments, not old nor necessarily reoccurring. They are my own created remainders, not meeting reminders sent from someone else. I am getting the impression the reminders which have already been snoozed a few (or many times) may become the ones which can no longer me snoozed or dismissed. This is just a theory. It also seems this condition exists sporadically. So far I just did the clean reminders launch and all seems well but I guess I have to wait to see if this fixes anything. For example yesterday I had a couple that refused to be snoozed or dismissed, kept coming back up. Today, everything is fine. I guess because those reminders have passed or something? So, those particular ones from yesterday eventually seem to stop, maybe because I closed Outlook and re-opened or shut the system down and the cold boot the next day fixed something? Thanks in advance for any assistance

    Hi Diane,
    This tools is wonderfull. I used it but my stuck reminder still will not disappear...
    Working with Win8.1/Office2007, I tried to remove one reminder as test and it worked but the stuck reminder does not disappear from the list using the 2 first deletion modes, and displays an error for the 3rd mode DELETE_HARD_DELETE :
    «
    Error:
    Code: MAPI_E_UNKNOWN_FLAGS == 0x80040106
    Function ((LPMAPIFOLDER) m_lpContainer)->DeleteMessages( lpEIDs, lpProgress ? (ULONG_PTR)m_hWnd : NULL, lpProgress, ulFlag)
    File FolderDlg.cpp
    Line 708
    »
    Any idea how to nuke this reminder?
    Thanks for your cares.
