So I'm deploying Office 2010 to our group and our office assistant/receptionist helps manage several calendars and he was able to do so witout problem after the upgrade from Outlook 2003 to Outlook 2010. But the other day out of the blue he started to not be able to add meetings to peoples calendar, but that now works in part to the /cleanfreebusy switch, but he is not able to delete meetings from other peoples calendar. He keeps getting the following error mesg: "Could not complete the deletion. The items may have been already deleted or moved."
He does have full editor access for the calendars. The other users are still using Office 2003, except for two (who are using 2010), but he has the same issue with their calendar also. Now here is the really strange thing, he is able to drag and move (holding the shift key down) the appointment from the users calendar to his and then it's gone from the other persons calendar, then he is able to delete it from his calendar without any issues.
I have removed and recreated the Outlook exchange mail profile. The meetings he puts on peoples calendar does show on those peoples calendar. I've run every Outlook command
line switch I could find.
Help!
