The company i work for uses Exchange 2010 with a couple of domains mydomain.net and mydomain.nl. Recently they bought a few office 365 licenses for use with the mydomain.eu domain.
Mail send from a mydomain.eu mailbox needs to be handled by the Exchange server and delivered to an application inside the domain where the Exchange server is in.
I added the mydomain.eu as an accepted domain on the Exchange server. It seemed to work fine. However, users report that they cannot send mail from inside the company to the mydomain.eu mailboxes in the office 365 environment.
So to make my question clear;
After adding the office 365 domain as an accepted domain on the Exchange server, users that are on the same LAN as the Exchange server can't send e-mail to the office 365 domain.
Can i get this to work somehow?
