I have a new Exchange 2013 server, Outlook 2010 users have connected fine. Outlook 2010 prompts for a login and takes it and connects. OWA also works fine. However when I try to connect with Outlook 2007 it prompts for username and password and won't
accept the password. I migrated a few other users who are using Outlook 2007 and they were unable to connect at all. I have a internally signed cert on the new Exchange 2013 CAS server. Any suggestions would be greatly appreciated.
