One of my users is trying to update an appointment on his calendar by inserting a file into the appointment. When he tries to save the appointment he gets an error message "The item cannot be saved to this folder. The folder was deleted or moved, or you do not have permission. Do you want to save a copy of it in the default folder for the item?"
"To eliminate this issue, archive or delete messages until the size of the mailbox is iess than the limitation imposed by the administrator or is less than two terabytes, whichever is smaller."
Here's some background info. We run Exchange 2010 with all the updates/Service Packs installed. We run Outlook 2007 in online mode (regulatory reasons). the user's mailbox is 50 MB below his limit and the attachment he's trying to save is less than 500 KB. Oh and the person affected is my boss who's trying to update a meeting he's had on his calendar for months.
Any guidance you can provide is greatly appreciated.
