Cannot dismiss or snooze reminders

I seem to have encountered a zombie reminder that doesn't want to die. A few weeks ago I had an issue where I had a reminder from weeks gone by pop up in my Reminder window in Outlook 2010. Due in: 2 weeks overdue. Weird, I thought.

So I did the usual 'Dismiss'. 2 seconds later:

"1 Reminder, Due in 2 weeks overdue".

Weird, I thought. So I tried snoozing it.

Not 2 seconds later:

"1 Reminder, Due in 2 weeks overdue".

Ok, this is getting weird. Let's try 'Dismiss All'.

"1 Reminder, Due in 2 weeks overdue".

Fine, fine, you win Outlook. Let's open the item and delete it.

"1 Reminder, Due in **3** weeks overdue".

Ah, now the previous reminder in the series is popping up. Let's delete that one too.

"1 Reminder, Due in **4** weeks overdue".

I ended up having to delete all past occurances of a weekly reminder before the reminder removed itself.

It's now a few weeks later, and what do I see?

"1 Reminder, Due in 2 weeks overdue".

Does anyone know if this is a known bug in Outlook 2010 Beta, where recurring events with reminders start zombifying themselves, and won't stop reminding me they exist til I decapitate (delete) them entirely?

Solution 1:

If it is still occuring you can always start outlook with the switch /cleansniff which should get rid of duplicate reminders. Worth a try. Then try /cleanreminders to clear and reset all reminders (eg show you all future ones which you have snoozed or dismissed etc). Use switches as part of command to start outlook, eg:

<path to outlook>\outlook.exe /cleansniff
