Replace ogranizer on orphaned appointments Echange 2007

Oct 20, 2010 at 6:58 AM

Micrsoft recommended to me that i delete a user, recreate them and their Mailbox and restore all of the calendar data back into their mailstore and assured me this would not have any effect on the appointment assignments and permissions.  As I am sure you can guess what happened next.  All appointments cannot be modified or updated because they say the user doesnt have permission because the appointment thinks the organizer is someone else.

MS then tried to tell me that the use of the MFC MAPI tool may be able to overwrite those permissions.  You can imagine that I am leary to believe them especially since they failed at running it twice on the exchange server.

Can anyone help?!
