I have an exchange 2013 server running on a Windows Server 2012 R2 box that is also a domain controller and performs DNS. I have installed an SSL certificate for mail.domainname.com installed and listed as valid in ECP. When I try to connect a local computer running Outlook 2013 on Windows 7 I get asked for login and password which it won't accept. I have tried my user and my administrator credentials, either work.
It then says that "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
I can connect via OWA and don't get any certificate errors. My internal host name and external host name are both mail.domainname.com according to the Get-OutlookAnywhere | ft internalhostname,externalhostname.
Any help is greatly appreciated.
