Jerry,
Just some more background for you.
I set up the exchange account about 1 month ago.
The user that lost the folders had many folders and basicly lost half of the folders, 36 total with under 300 emails per folder (some had sub folders)
I still have the original folders under "On my Computer" but not the additions to the folders since I copied folders into users exchange account.
I'm not an expert at Exchange, but really good at finding solutions
Before moving to exchange all folders were Archived to hold only current year files
The user with lost folders has 2 other users whom share account via Outlook 2011mac and additionally 1 of the 2 access with iPhone.
Thanks
