Hi, I have a user that has reminders that pops up everytime you open outlook. this started after they synced with their pocket pc, which loaded duplicates of certain appointments. when you click dismiss you get the following. Cannot turn off the reminder. You may be reminded again. There is not enough memory available to preform the operation. I have tryed /CleanFreeBusy and /CleanReminders. To the best that i can tell this is a probleam with the mailbox on the exchange server. i get the same messige if i login as the user on another machine. im running an windows 2k with office 2000 and the server is running exchange 2000.
