OWA 5.5

Posted on 2005-04-18

We are migrating from NT4 with Exchange 5.5 to Windows Server 2003 and Exchange 2003. So far almost all the mailboxes are moved to the new server. We are still using OWA on the 5.5 server. Everyone who was moved can still use OWA. The mailboxes that have not yet been moved can also access OWA. However, when we create NEW USERS on the 2003 server and create a mailbox for them they cannot access OWA 5.5. From within the network, I can use the new servername/exchange and login just fine with that user. Since all users have not been moved yet what must be done to allow the new users to login to OWA 5.5.  I have ADC setup and the connection agreements work fine. I also added the new domain's  domain users group to be able to "log on locally" to the 5.5 server. All email still goes through the old server (incoming mail) and get properly sent to the new users mailbox on the new server. We just can't use OWA 5.5.
Any suggestions?

    The OWA 5.5 server looks at the Exchange 5.5 server for directory info, which is why all the current users are still able to connect. In theory, the OWA registry setting would need to look at your exchange 2003, then it would be able to find the old users and the new users.

    Try setting this registry key:

    set the server name to the E2K server name, and see if it works then. You can always set it back to the original if it fails.

    Do the new users use Outlook to access their mailboxes on E2K3?

    New users use both Outlook and OWA to access their email. Outlook is setup to look at the E2K3 server.

    what error message is received when the logon fails?

    Author Comment

    The Error message is 401.1 Unauthorized Access: Logon Failure

    When I use domain_name\Username the new users who were created on the new server log on just fine. The domain_name is a new domain. The E2k3 server is in a different domain than the E5.5 server.

    Even though all other users mailboxes were moved they don't have to put domain_name\Username, they just use their username and password. Is there anyway for the new users to only need a username? This is only a temporary problem until I get the rest of the users moved over and can have everybody use OWA on the 2K3 server.

    We ended up just moving the rest of the mailboxes and redirecting OWA. Thanks for your help.
