I am migrating from Exchange 2010 to Exchange 2013, the Exchange 2013 is built in a different Geo-location site with its dedicated domain controllers in the new site. I have confirmed the mail flow between Exchange 2010 and 2013 mailboxes. I am able to discover Exchange 2010 servers from 2013 environment via Get-ExchangeServer shell command. However, I am not to discover Exchange 2013 servers from 2010 environment.
I need to configure Outlook Anywhere and Service Connection Point (Autodiscover) on Exchange 2010 to accept connections from Exchange 2013 servers.
Any suggestions would be much appreciated, thanks!
