I have an issue with Exchange 2010 that I have never seen before. Two days ago, a user reported that a bunch of calendar items kept popping up on their screen as reminders in Outlook. I assumed a corrupt calendar item, ran CalCheck, deleted about 1,700 corrupt calendar items, and thought it was fixed. Then the items came back again.
I have tried everything I can think of:
- Removed all ActiveSync connections
- Deleted the mailbox and recreated it
- Rebooted my CAS and database server
- Attempted to purge the items with searches
I honestly don't know what else to do. About every five to ten minutes, roughly 140 calendar items populate themselves in this user's calendar, pop up as reminders, then delete themselves to the Deleted Items folder. It seems like something stuck in a queue, but I don't know where to look. Any help would be appreciated.
