I've added an Exchange 2013 (Windows 2012R2, Mailbox and Client Access) in my existing Exchange 2010 (Windows 2008, Transport Role) structure. Everything works fine, I can connect the users and send emails.
Unfortunately I've got no incoming emails as the Exchange 2010 Transport server doesn't seem to be able to forward to the Exchange 2013 server.
My Exchange 2013 server doesn't show on the server list of the Exchange 2010, while it appears on the 2013 console.
I'm sure I'm missing something simple and stupid... :-)
Thanks in advance for your help and advices !
