Overview:

Follow this KB article if you need to manually delete Outlook reminders.

How to:

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. 

Type: 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).

Use 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)

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

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, 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).
