Then, close Outlook, go to Start, right-click it, and choose ‘Run’ to open the ‘Run’ dialog box.

There, type the following command and then press OK:

outlook /clean reminders

Your problem should be resolved by now. If it doesn’t, use the following command and see if it helps:

outlook /reset folders

Enable Reminders Support for Pst-file

If all the above methods fail to work, you can use this method as a last resort.

Open any pst-file by choosing File > Open & Export > Open Outlook Data File. This will enable reminder support for the pst-file.

Right-click on the top of the pst-file and choose ‘Data File Properties’ option.

When a new window opens, go to the ‘General’ tab and check the box next to the option reading ‘Display reminders and tasks from this folder in the To-Do Bar.’

Restart Outlook and see if the problem is resolved.
