Outlook Wont Connect to replacement Exchange Server

I'm not sure what i'm missing here, but we changed over to a replacement exchange server. For some reason, outlook is trying to resolve and connect to the old server, even though the mailboxes, and the roles are all configured on the new one.  Everything else seems to be OK.  Mail is moving, ActiveSync is working, but Outlook wont connect to Exchange.  What am I missing here?

Internal or External? I take it is most likely internal..

Make sure the SCP (Service Connection Point) for AutoDiscover is pointed to either the replacement CAS, or a namespace that points to the CAS (, then have an A record in the forward lookup zone (DNS) that points to the CAS).  This is most likely the reason for this.

Here is how to view the SCP:

OK, per that doc, there were a couple goofs in there.  Should I go ahead and make the corrections?

Well for the binding, it only had https://servername.local instead of https://servername.domain.local.  And the keyword attrribute had a bunch of numbers in there, instead of the site=default first site key.

The SCP you can fix easily... If there is a single server in the environment, just change it to the proper server. Multiple servers is a tad bit different.

Before changing the keyword context, confirm the site name within AD sites and services..

That I did.  And I wound up calling Microsoft on it.  That was part of it, and also that the RPC was not assigned to the databases on the new server.  After running that command, the outlook clients fired right up.  So we're good! :)

Thank you for the help!  Much appreciated!!
