I'm migrating from Exchange 2003 to 2007. I've installed an Exchange 2007 server which runs CAS, HUB and Mailbox roles. Most mailboxes have been moved to the Exchange 2007 server.
OWA works fine, ActiveSync works fine and Outlook Anywhere works fine externally for laptops that are members of the domain. However, non-domain computers can't connect using Outlook Anywhere.
I have a SAN cert with webmail.company.com as the common name and autodiscover as an alternate name. The DNS for webmail.company.com still points to the old server so I'm pointing users to autodiscover.company.com for Outlook Anywhere. As I say, this works fine for domain member computers.
Does anyone have any ideas why this wouldn't work with non-domain member computers?
Many thanks in advance.
