I installed a new Exchange 2007 Server that ran concurrently with
an Exchange 2000 Server. I gradually moved all the mailboxes until I
finally had them all. There was still the problem of a certain
application that had server information hardcoded in that finally got
changed this week. Everything is now on the New Exchange Server,
including Public Folders and offline address books.
So I shut it down to see if everything would function ok. It did,
with the exception of a single client computer. When I shut down the
2000 box, Outlook will receive EMAIL but will not send. It asks for a
password for the user to logon to the old Exchange Server. The
Outlook client is set up exactly the way every other Outlook Client
is. The Version is Outlook 2003.
Send Connectors are on both Servers. They route to a spam filter I
use as a smart host.
No Routing groups exist between the two servers. I deleted them
earlier this week.
Why is this one computer still trying to route through the old
exchange server?
