I've setup a test environment with Windows Server standard 2012 R2 and Exchange Server 2013 SP1...
In- and outbound SMTP works fine, as well as connecting with OWA and Mac Outlook client...
Oddly though when setting up an Outlook 2013 connection....it recognizes the email address correctly, but later on can't connect and shows a dialog to enter the server and email account manually....though the profiled fields show something like:
Exchange Server: 32857e39-d12d-4adf-b4b9-83822442a3db@mydomain.net
Mailbox: =SMTP:richard@mydomain.net
When I fill in the right fields....it won't connect and falls back to the values above...
Something wrong in the Exchange setup?
