Your mailbox has been temporarily moved on Microsoft exchange server.

If you get this error when opening Outlook 2007:

"Your mailbox has been temporarily moved on Microsoft exchange server. A temporary mailbox exists, but might not have all your previous data.You can connect to the temporary mailbox or work offline with all of your old data. If you choose to work with your old data, you cannot send or receive e-mail messages."

Then you must recreate the user's profile completely to rectify it.
