We are experiencing an interesting problem with OWA with the first and only Exchange 2007 server. First our setup, Exchange 2007 SP1 running on Windows 2003 SP2 server. We moved a couple of test mailboxes over to the new server, which went throuhg without incident. We are able to log onto the mailboxes with Outlook 2007 but when we try to hit them via OWA, internally only at this point, we are unable to connect to the mailbox. If we move the user account to a different OU in AD we can get into the mailbox just fine via OWA. We are still able to get into the mailbox via OWA when moving the account back to the original OU. We did try to move the account out of the OU and then back to the original OU before accessing the mailbox with OWA but that didnt work either. It seems we have to move the account login via OWA and then everything works fine. Has anyone else encountered this problem? thank you, -- Andy Network Admin
