Unable to receive email from external domain ?

Last Modified: 2015-11-25
Hi All,

I've got this strange issue where I cannot seems to troubleshoot, hence I need some of your help here.

Background: Exchange Server 2010 SP3 on single AD domain.

My head office AD domain is simply domain.com, while the Exchange Server has multiple different accepted email domain for example Company1.com, Company2.com and CompanyX.com

Testing 1:
When I send out email from itsystemengineer@domain.com to reception@Company1.com it was sent successfully from Outlook, OWA and ActiveSync but somehow it didn't reach or appears in the OWA/Outlook of the Reception mailbox at all.

Testing 2:
When reception@Company1.com sent from Outlook, OWA and ActiveSync to my email itsystemengineer@domain.com it appears in the OWA/Outlook mailbox.

Note: Nothing in the queues, exchange seems to deliver, it just doesn’t. Message tracking gave me an error.

Any kind of help would be greatly appreciated.
