After a series of nasty mishaps, I needed to create a new Entourage profile and re-populate my calendar by resynching it with my Exchange Server.
Now I'm receiving multiple notifications for a single appointment -- two or even four at once. (Perhaps four is due to the intermediate 'reset' attempts I made before discarding and creating a new profile.)
Reviewing my calendar I see only a single appointment, not multiple appointments. Checking my Outlook calendar confirms only a single appointment. My local calendar is completely empty.
Is there a separate Entourage database for reminders that I can clear or resync? Is there somewhere else for calendar appointments to live where I'm not looking?
