Exchange 2013: Correctly setting up a Send connector.


You probably recognize me well from this looong migration.

Anyway, I am migrating from Exchange 2010 to Exchange 2013.

I need to configure the Exchange 2013 Internet Send connector.  Currently mail seems to be still routing from the Exchange 2010 server.  

I am a little unsure as to whether I need to add a Source server.  When I select "+", what is listed are the 2010 CAS and the 2013 Mailbox server.  Can or should the source server be the mailbox server?

Thanks in advance.

Yes..  The source server is where the mail is going to be sending from.  Since your 2013 server is multi-role, it is almost certainly running the HT service which is what will be doing your mail sending.

With connectors on each server active, you'll see mail that originates on 2010 will go out the 2010 server, and mail originating on mailboxes on 2013 will use the 2013 connector.  After you see mail flowing from the 2013 server, you can remove the 2010 connector, and 2010 will begin to send mail to/through the 2013 server which will then send it out.

Thank you 172Pilot.  Just to re-confirm because I want to absolutely sure.  In my case, my source server will be the MAILBOX server correct?  That is the one being listed (along with the 2010 CAS).
Yes..  It wont let you put a server in that source entry unless it is running the right role to have it work..
