Outlook Only Starts in Safe Mode?

Slipstick Systems

› Problems › Outlook Only Starts in Safe Mode?

Last reviewed on July 31, 2019     202 Comments

Applies to: Outlook 2007, Outlook 2010

Outlook 2010

If your problem began on December 8 or 9 2015 and affects Outlook 2010:

In Outlook 2010, all of my options were reset to their defaults and when I change them, the changes don't stick. As soon as I close Outlook and restart it, everything is back to its default.

This is caused by installing KB3114409 - it causes Outlook to run in Safe mode, which uses the default settings. Your customizations aren't lost, they just aren't being used when Outlook is in Safe mode.

Microsoft released this update to fix the problem: December 16, 2015, update for Outlook 2010 (KB3114560). It is highly recommended that you install this update instead of uninstalling KB3114409.

Microsoft removed the update, so users who haven't installed the December updates yet won't be affected. Users who are affected should install the hotfix December 16, 2015, update for Outlook 2010 (KB3114560).

A second option is to set a registry key to disable Safe mode. If you are in a hurry, this is obviously the faster fix but you won't be able to use Safe mode in the future (for troubleshooting) until you remove the key.

To set the registry key:

  1. Open the Registry editor by pressing Windows key + R. Type regedit in the Open: field. Then click Ok.
  2. Browse to HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook\Security\
  3. If any key in the path is missing, you'll need to create it. Right click on the last key, choose New, then Key and type the key name.
  4. Right click on Security key and choose New, and then DWORD Value.
  5. Type DisableSafeMode, and then press Enter.
  6. Right-click on DisableSafeMode, and then click Modify.
  7.  In the Value data box, type 1, and then click OK.
    Set the registry key
  8. If you have 64bit Windows and 32-bit Office, also add DisableSafeMode, Value: 1 to this key: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Office\14.0\Outlook\Security\
  9. Restart Outlook or reboot the computer.

If you don't want to edit the registry, you can use this reg file: DisableSafeMode.reg DisableSafeMode.reg for Outlook 32 bit on Windows 64-bit

Uninstall KB3114409

To uninstall updates:

  1. Open Control Panel
  2. Begin typing Installed Updates in the Search Control Panel field at the top right.
    view installed updates
  3. Click on View Installed Updates on the left
  4. Begin typing KB3114409 in the Search Updates field in the top right
    select and uninstall the update
  5. Select it and click Uninstall in the bar above

Outlook 2007 or 2003

The original reason this article was written in 2011 was caused by an issue with the search service. Outlook 2003 and 2007 are affected by this problem.

Solution: Repair your Office installation and run scanpst on the data file.

The problem is caused, in part, by the 'Windows Search' service. This service provides Outlook's Instant Search and Window's file search features. For a quick fix, you can stop or disable the Windows Search service.

To do this, open the Administration Tools folder in the Control panel and double click on Services. Look for Windows Search in the list. Double click it, then click Stop and Apply. You can also right-click on Windows Search and choose Stop. The next time you use Instant Search or Windows Search, the service will restart. To disable the service for a longer period, select Disable in the dropdown and click the Stop button, then Apply.

Please note: when you disable the search service, Windows File Search and Outlook's Instant Search won't work. Stop the Search service only so you can use Outlook in "normal" mode until you have time to repair it.

Stop the Windows Search Service

In Windows 7, you can type Services in the Start menu's search command or in all versions, type Services.msc in the Run command.

    Diane,
     
    I see you on these forums a lot and an having an issue that appears to have no history. Outlook 2019 is stuck in a repair loop which finds no issue with the .PST but continues to say it has a problem at every launch. Outlook will not run. I have tried everything (new profile, uninstall/reinstall, clean registry, etc.) and am now to the point where only killing the trigger will stop the issue. Where is that trigger? Registry key? I hate to call MS for a fix. . .
     
    Thanks,
    Ron

    I have an interesting problem with Outlook 365. This problem started about 8 months ago and not matter what I tried, the results was the same. I've attached some screen captures that shows the dialog windows that come up. Which to me makes no sense at all. I say this because there are no other windows or programs open, my PC is running an i7 with 128GB of RAM, and 1TB HD for a system drive. I've reinstalled Office 365 with Outlook several times, but alas, that did not help. When trying to use the safe mode option, outlook does startup, but I get a repair notification and then it shuts down. I checked with Microsoft but found no solution, just a good luck with your problem. You will need to preform a total clean installation of Windows. I am hoping someone has a solution because I really don't want to do a clean install of Win 10.

    After 2 months of Outlook 2016 prompting to start in Safe Mode, then crashing (not responding), I tried the simplest thing ever and it worked.
    Control Panel, Internet Options, Advanced, Reset (and delete).
    Bingo. After 2 months of banging my head on my desk, Outlook is stable.

    Hello all. For those who have had the issue with Outlook opening in Safe Mode, we found the issue. Microsoft released a hotfix that was corrupt – hotfix for KB3114409. This hotfix only affects machines with Office 2010 installed, anyone running Office 2013, and specifically OUTLOOK 2013, should not have the issue. They since have pulled it from their update servers – but we do need to remove from affected machines. To do so, please follow these steps:

    - Click Start – Control Panel – Programs and Features

    - Click “View Installed Updates” on left

    - In the search bar on the top of the “Installed Updates” page, search for *KB3114409 (keep the asterisk in the search criteria)
    - When you find the update, click “uninstall”
    - Reboot when finished

      You no longer need to uninstall it - they released an update to the update or you can set the reg key.

    Hi

    I was a bit confused by this article since it refers to a hotfix, uninstalling an update and a reg tweak, so I thought I'd try the KB3114560 hotfix first.

    Thankfully it works fine and resolved this most annoying safe mode issue. :-)

    I do wonder how all the supposed "productivity improvements" that are apparently included with new Microsoft s/w features are undone at a stroke when these types of "fixes" are released without proper regression testing, and cause several hours of frustrating searching for solutions and fruitless diagnostic & repair work.

    That said, I knew once I saw the mention of Slipstick in some search results that I'd have some useful information, having known it as a high quality and most valuable resource since inception (Sue Mosher days). :-)

      The hotfix is new and came out a week or so after the bad update. I should rewrite the article tho - and remove the uninstall instructions now. Both the reg fix and the hotfix do more or less the same thing but with the correct configuration. There are a few people who uninstall the update and it's reinstalled - they definitely need the hotfix.

    I never had the offending KB installed so the corrective KB from MS was worthless. Editing the registry following your instructions worked. I guess it was too much for MS to package into its own update.

    Thanks Diane,
    No-one here knew the solution. The registry tweak worked perfectly. Had to make new key values first btw, since neither security nor DisableSafeMode existed, but after adding them on a W10 64 bit machine with office 2010 32 bit the problem of safe mode disappeared.

    Thank you so very very much, Diane Poremsky! Mega kudos!! Too bad yours wasn't the top response in my list of searches over the past week. None of the other posts offered solutions that worked and when yours mentioned that it applied to a problem that began around December 8th or 9th, my hopes were raised. And as soon as I uninstalled KB3114409, voila, my Outlook 2010 was fixed!

    I am curious/disappointed as to why Microsoft did not send out a follow up update to correct this once they became aware of the problem.

    I will certainly be exploring Diane Poremsky's other work as she scored big time on relieving me of this irriatating problem I've been wrestling with. Thanks again, Diane!

      If the path doesn't exist, you need to create it - right click on 14.0, choose new > key - work your way down the path.

        is this a corporate computer? It sounds like its locked down for changes, which is common at corporations. Oh, are you signed in with a user account that doesn't have admin rights? That will cause this problem on home computer.

        It sounds like your windows account doesn't have the permissions needed to edit the registry - the account needs administrator permissions.

    "! Task ‘MyName@outlook.com’ reported error (0x8004102A): ‘Error with Send/Receive’." What does this mean please, and is it related to the KB3114409 update issue? Thanks.

      Was your account migrated to the new server? What account type (POP, IMAP, Outlook connector, Exchange) is it? If it was migrated, the outlook connector no longer works and you need to remove it from your profile and use auto account setup to add it back. More details: https://www.slipstick.com/outlook/outlookcom/outlook-com-migration-status/

        Hi Diane, I'm on a home computer - I don't have a server. I think it's a MS Exchange account (the one that MS gives you now instead of a Hotmail account). Account Settings say 'MAPI' but I think I installed Outlook connector a while back (so I could synchronize with my Windows phone). Does this sound right to you? Sorry, I'm not that up on all this stuff. If you can tell me where I can find this information, I can look it up and tell you more precisely. BTW, I have another email account (POP) and I don't get this error message with that one. Thanks.

      • Diane Poremsky says

        December 14, 2015 at 3:22 pm

        Ok... if the account was migrated to the new server, you need to remove it from Outlook and uninstall the connector - the connector will no longer work. Then use auto account setup to add the account back to your profile.

        Diane, I just went into my Outlook account and did a Send/Receive and I'm no longer receiving the error message! It either fixed itself mysteriously or MS has fixed it. Either way, looks like I don't need to do anything (at least for now). But, just in case, can you please tell me (1) How to uninstall the connector, and (2) Where do I find the Auto Account Setup? Thanks again!

I am stuck in safe mode, I am going to try the edit registry method although that is the last thing I want to do. If it was installed.. and I believe it was because since 12//9/15 I am stuck in safe mode and I hate it

      download it and if your web browser saves it with a txt extension, change the extension to reg then double click to run it. You'll probably be asked to ok a dialog a few times - click ok or yes as needed. Then restart outlook.

      If you aren't showing file extensions - the icon for a reg file has greenish boxes over a white paper icon, txt is a lined paper icon. If you see the lined paper, you need to show extensions. If you use windows 8 or 10, tick the box to show file extensions on the View tab in Windows Explorer.

    Thanks, removing this update really helped, it showed to me that the add in for indexing also has been a problem but in safe-mode couldn't make any adjustments. But after removing the update this has been gone alright and everything working well.

    I removed update KB3114409 from my computer and my problem was instantly resolved. Thank you for this information. However, I am angry at Microsoft for issuing this update without testing if further and not advising the public of the problem afterwards.

    Thank you, but unfortunately that did not work either. I've been searching online for over a week now and I still can't get it to work. I tried disabling all add on, repairing, start windows with all drivers disabled, uninstall and reinstall, create new outlook file, create new user on PC, removing latest updates, and formatting PC but for some reason, it works until updates are made to windows. after that, only safe mode works.
