We have an exchange 2007 server in sydney. I have added a second exchange server 2007 server located in melbourne connected via a VPN.When I transfer a mailbox to the new server they dissapear from the global address book. The relocated users are no longer able to use outlook on the Terminal Server or OWA in sydney. Outlook on thier PC's appears to work fine.
We did have a 2003 server that was ungracefully removed from the domain a few years ago but I dont know if that is relevant.
Thanks in advance.
