Exchange 2010->2016 migration - Cannot achieve Exchange server authentication
Hi,
I'm in the middle of a migration/co-existence with 2016/2010.
I cut over the DNS settings this morning.
In the Queue viewer on the 2010 server, all looks good.
But in the Queue viewer on the 2016 server, I am seeing a large number of messages in the "site:default-first-site-n
Cannot achieve Exchange Server Authentication: Last Endpoint attempted was (IP address of one of my 2010 servers).
Help please!
Not sure what to do to get this queue cleared out.
Thanks!
Nacht

Ok. I think I got it.
I made a connector on the 2010 machine and added in the IP address of the 2016 machine. My queue started going down immediately. I don't understand why I had to make that connector though, I though the mail flow between these machines was automatic.
I don't see how creating the connectors could have hurt anything though. So I think I'm good. Thanks!

Can you send and receive emails?
Have you created the send connector in Exchange 2016?
