Changing Exchange's Mailbox Location

When you create a mailbox in Exchange for e-mail, you specify the file where you want to mail to go.
You cannot change this in Exchange afterwards.

If you want to change the file name or location::

1. Start Regedit
2. Go to HKEY_CURRENT_USER \ Software \ Microsoft \ WindowsMessaging Subsystem \ Profiles
3. Go to the profile you want to change
4. Go to the section that has the file location for your mailbox (*.PST) file in the right hand panel
5. Make the change to file location or name
6. Restart Exchange
