How to Change the Type Attribute

The Type attribute can only be changed by running Setup.exe from an Enterprise Edition CD (Srvmax.exe if using Select CDs), and clicking Reinstall. This changes the Type attribute within the Dir.edb file, giving you an unlimited store.

NOTE: You need to reapply the last Exchange Server service pack that had been applied to the server before the reinstallation, after the reinstallation is finished.
