Exchange 2013 Message Loop
Posted on 2016-11-03
Hello EE Community
here is scenario that i am dealing with exchange 2013
the company already has an exchange email service through a 3rd party..we'll call it domaina.com
a few cloud servers were setup separately elsewhere with active directory using the domaina.com, one of those servers was setup with exchange. this is for another domain that they have we'll call it domainb.com.
to setup an email for domainb.com it obviously gets a domaina.com ad account.
sending and receiving using the domainB.com alias works great to anyone in the world EXCEPT when trying to send to domainA.com
that's where the loop occurs and it that cant leave the server because it thinks a domaina.com email address is within its realm.
my question is has anyone dealt with a situation like this or would active directory have to be reconfigured with the domainb domain name?
Thanks again fellas and ladies
