I have an exchange mailbox (administrator) that is has way too much data, 45 GB. I used the Exchange Task Wizard to delete the mailbox for the account. After deleting the account, I used the wizard to recreate it. When looking at the account via outlook, I don't see any data in the mailbox. Yet, my server has not reclaimed the disk space, and,when looking at the mailbox in system manager, I sitll see nearly 49,000 items/45 GB of space.
