we have installed an Exchange 2013 that is co-existing with Exchange 2010. I've created an test-user that is placed on Exchange 2013 and I can connect with the user on owa intern. But when I try to connect this user to Outlook 2013 manually, it fails with this message:
Outlook cannot log on. Verify you are connected to the network and are using the proper server and mailbox name. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
I've checked that the SRV autodiscover dns record i pointing to the Exchange 2013 server and it looks fine.
When I type https://SERVERNAME/autodiscover/autodiscover.xml
into my IE, it prompts me for login and when I type in my credentials, it shows me this:
<?xml version="1.0" encoding="UTF-8"?>
-<Autodiscover xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">-<Response>-<Error Id="746590105" Time="08:28:27.1771287"><ErrorCode>600</ErrorCode><Message>Invalid Request</Message><DebugData/></Error></Response></Autodiscover>
Which should be right. I haven't opened up for owa external yet.
What am I missing here? I just want it to connect to our Outlook.
