All, when we as domain admins attempt to open another users folder by going to File --> Open --> Other Users Folder, we must enter the username@domain.com to access their mailbox, however, if we enter just their username, we get the error: "Unable to display the folder. Cannot open the mailbox for this user because the user does not have a server mailbox" Previously we were on E2k3 box and moved to another E2K3 Box, same domain, same organization, just a different servername. Any ideas?
