You need to contact Mail Marshal as I have already told yoU!

Is Mail Marshal configured to only allow registered addresses ? If yes then configure Mail Marshal to load / sync the new addresses from you active drectory.


Hello taked to Mail Marshal and seems the issue is not with it, all the routing are working fine

Issue is not with routing, does Mail Marshal check for users smtp address against a database before forwarding it into exchange ?


Hello, So I went through the Marshal log and as i suspected MailMarshal processed the email correctly.
So it looks like it is an issue with exchange servers rather than with MailMarshal.
