Hi:

A user reported to me that randomly they notice draft folders in their Deleted Items, like Draft1, Draft2, etc.  Mailbox auditing revealed that another user who has delegate access the mailbox is generating these draft folders.  I think what might be happening is that the user with delegate access keeps calendar invites open for a period of time, after which an autosave executes.  The autosave perhaps generates a draft folder then after the calendar invite is saved/sent the draft folder is moved to the original user's Deleted Items folder.  Is this a known issue or anyway to stop this behavior?

Patient:  Doctor, it hurts when I do this.

Doctor:  Well don't do that!
