Exchange 2007 and 2013 Coexistence cannot send email from 2013 to 2007.

I have 2013 running with a test user.  The test user is able to send and receive email to the internet using OWA but cannot send email to internal user on 2007.  It can receive from internal 2007 user.

I also get this error when opening Outlook 2013 with this test user on Exchange 2013:

Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened.  You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with Outlook data file (.ost).

I have been following this guide and am at the testing phase:

Do I need to add the server to my ssl? server.domain.local  I know I had to in 2007, but do not see that for 2013 documentation.

On the exchange 2007 server, can you make sure that the default receive connectors haven't been modified.
I have seen this issue in the past where the default- servername receive connector has been modified. If so recreate the receive connector.
Also check the message queues on the exchange 2013 server.

I found the issue. I was manually trying to configure an outlook client. If I used auto discovery it worked.
