I had a server die. It is gone forever.

It is still listed in the servers folder of the first administrative group in the Exchange System Manager.

When I click "all tasks > Remove Server" I get the following error:

The Server "SERVERNAME" cannot be removed because:
-One or more users currently use a mailbox on this server. 
These users must be moved to a mailbox store on a different server 
or be mail disabled before uninstalling this server.
Facility: Exchange System Manager
ID no: c103f492
Exchange System Manager

Any help would be MUCH appreciated.

I cannot access the mailbox stores anymore and I do not care about the lost mailboxes. We deleted the inactive and old users as well. So I am stumped on this one. I just need to remove the old machine.

THANKS!
