New Outlook profiles won't connect to Exchange 2007 from Outlook 2007. Able to ping server by hostname and IP Able to access OWA All services are running on the standalone Exchange 2007 server Existing Outlook 2007 users/profiles are able to connect to the Exchange 2007 server without any problems. New Outlook profile settings are the same as the old profile settings.
I've recently p2v'd my Exchange server, created a new DC, upgraded DFL and FFL to 2008 r2, decommissioned 2 2003 DCs, added a 2008 r2 DC and set that server as the sole DC and DNS server. So there has been a few changes since I last tried to create an Outlook profile :/
I think in the past when I'd reboot the Exchange server one of the MS Exchange services (I can't recall which) wouldn't be started automatically and would exhibit similar symptoms. The unit is in production so I don't want to restart services without knowing the impact.
