While configuring Office Outlook 2007 in the workstations to access my Exchange Server 2010, I stepped in a problem.
None of the workstations are part of the domain, but they can access their Exchange mailboxes by providing username and password nevertheless.
One of them though, fails to connect to the server. It doesn't even ask for a password, it just says there was a problem with the connection.
In this workstation in particular, the local username and password are the same as in the domain, the only difference is the full username: station\username against domain\username. It led me to believe this must be the cause of such conflict.
Is there some way I can make my server understands anything\username as domain\username in order to workaround this problem? I read somewhere it was possible, but I can no longer find this article anywhere.
domain\username
or[email protected]
... then that's not the problem. (I highly doubt that's the problem in any case, as a mismatched user principal name (UPN) is a will return a standardincorrect username or password error
, not a "connection problem" error.) My guess would be authentication type - NTLM not being accepted by the server, or a Kerberos authentication issue from that workstation. Whatever the cause, you'll need to dig deeper than the apparent username and password similarities. Check the logs.
