I have a user who has Outlook 2007 and Exchange 2003 (SBS). I'm having problems his workstation intermitantly popping up a login screen. Sometimes Outlook will launch without a problem and others the login screen continually pops up (no passwords work). He ends up restarting and then it seems to work after 1 or 2 reboots.
I am new to this customer so I don't know much about how it was initially configured except that he previously was setup to connect to a hosted exchange server with a third party vendor.
He is configured to connect to his Exchange server (which is local in his office) and a standard configuration is used for the exchange profile on his workstation. He does have some pop accounts configured too, all of which test successfully.
Anyone have any ideas why the login screen might come up intermitantly? Could it be related to previous configurations to the hosted exchange, and if so where would I check to change these settings other than the profile.
