I have Exchange 2003 and Exchange 2007. There used to be two Exchange 2003 back-end servers, but one of them was decommissioned and Exchange 2003 software was removed from that server. Now, I need to restore a mailbox that used to be on that server. I know I can do RSG on the remaining Exchange 2003 server, but I believe the fact that Exchange 2003 was gracefully removed from the other server, has removed the database information from AD. When I try to select databases to restore for the RSG, I don't see the database that I'm looking for.
Does this mean that my only option is to create a separate environment with the server that was removed in order to be able to restore this data from tape? I'd appreciate it if someone can confirm and give me guidance as to what my options are. Thanks.
