There are two types of users: those who want reminders from every folder and data file in their profile and those who don't. Beginning with Outlook 2007, Outlook supports reminders in any folder and across additional .pst files while Outlook 2003 and older support reminders only in the default folders within the default mailbox or data file (unless you use an add-in).
If you aren't getting reminders from other pst files in Outlook 2007 and up, you'll need to enable reminders in the Properties dialog.
Right click on the top of the pst file and choose Properties, then enable the option to "Display reminders and tasks from this folder in the To-Do Bar". You'll need to restart Outlook for the changes to work.
When the 'Display reminders' setting is not enabled, you'll see the following warning message when you set a reminder or flag an item in a folder within the data file: “The reminder for “<subject>” will not appear because the item is in a folder that doesn’t support reminders. Is this OK?” (This message may also appear if you create an appointment in an iCloud calendar (if using the icloud addin), you can ignore the message.)

Disable Reminders in Other folders
I've had several people ask if they could revert to the Outlook 2003 behavior, where reminders did not fire from non-default folders. Unfortunately, this isn't possible. If the data file is a delivery location (in Account Settings, Email accounts tab), reminders will fire from all folders. If you deliver an account to the pst file, reminders are enabled by default, plus tasks and flagged items in the pst are displayed in the To-do bar.
If you don't want flagged items or tasks from other pst files displayed on the To-do bar, create a custom view to show only items from certain folders or data files. If you want to disable reminders in non-default folders, either don't set reminders on the items or move them to a new pst file (and disable the option to display reminders).
We have a VBA code sample at How to Remove or Change the Reminder on All Day Events that can be tweaked to remove default reminders on appointments created in other folders.
When I view Data File Properties, I do not see the option to display reminders. See attached. Windows 10, Outlook 2016.
You'll only see the option if no mail is being delivered to the pst file. If mail is delivered to the file, reminders are enabled automatically.
It would really help ifyou could clarify PST file. We are all that computer savvy!
it's an Outlook data file... its used by pop accounts and AutoArchive.
this is very helpful. thank you.
I am using Outlook 2010. There are 2 pst files. Neither of them has the check box to enable reminders in its properties. Very frustrating.
By the way, this issue just started. Reminder have always worked just fine until today.
is mail being delivered to the pst files? if they are set as the delivery location in file, account settings then they are included by default.
I had the box checked on my PST but it wasn't showing up in the to-do list. I unchecked the box, restarted outlook, then rechecked the box, restarted outlook again. Now it works.
Re: "If you want to disable reminders in non-default folders, either don't set reminders on the items or move them to a new pst file (and disable the option to display reminders)."
Thanks Diane, this was a particularly helpful suggestion for me. Ever since I started using Outlook 2013 I've been trying to compensate for the wrecking of the Journal functionality from 2010 and earlier. What I had been doing until now to track time I spend on things was I had a Calendar folder called "time log" and I would drag tasks or appointments or emails into it (via a shortcut I added to the Shortcuts bar) and then type in the time I start plus the time I finish. But each one would generate a reminder, and every time I would have to dismiss it (I don't need reminders for things I'm already working on!)
But I tried your suggestion of just creating a new .pst file and moving my "time log" folder there, and I recreated my shortcut and it worked perfectly.
You could use a macro to do this too. See the first macro at https://www.slipstick.com/developer/code-samples/create-outlook-appointment-from-message/
I've tried everything you and others have suggested, and still can't enable simple reminders in a calendar.
I have the default calendar that was created by Outlook, and a second calendar paired with an account (hotmail) that is used only for syncing calendar and contacts to my Android phone and instance of Outlook on my work computer. Everything worked fine with this setup before I upgraded to Outlook 2013 -- reminders could be set in both calendars, those would sync to my phone, etc. etc. Now I get the ridiculous "item is in a folder that does not support reminders" message.
There is no enabling check box in the properties dialog for the .pst folder.
Please help!
You should get reminders from Hotmail unless they changed the behavior since I last checked. Is the Hotmail data file enabled for search? Click in the Search box, go to Search Tools, Locations to search. Is it checked?
I also had the "item is in a folder that does not support reminders" message. Most of the other help and answers on the web didn't specify that you must right click (context click) on the top most folder to get the "Display reminders and tasks from this folder in the To-Do bar" check box. That check box does NOT show up on the Task Item but rather in the Data Properties of the top most folder above the Task Item.
This may be specific to Outlook 2013 which is what I'm using.
It was annoying not to find this answer so I hope my explanation helps others.
