We have setup Active Directory forest trust and we used FIM2010 R2 for GALSync. All the contacts have been created in the two forest. from one forest I can pick the contact from the address book and send an email without problems, but from the otherside I try the same but the emails are bouncing.
On the bouncing emails, I can see that the originating domain is added automatically to the contact, I don'know where it comes from. this how the error message is generated:
Generating server: MBX.sendingdomain.local (Sending Server)
IMCEAEX-_o=Sendingdomain_ou=Exchange+20Administrative+20Group+20+28FYDIBOHF23SPDLT+29_cn=Recipients_cn=4fa2eac26060455ba1247480dde343d7-test+user1@sendingdomain.com
Remote Server returned '550 5.2.0 RESOLVER.ADR.BadPrimary; recipient primary SMTP address is missing or invalid'
Original message headers:
Here the Sendingdomian is where the email is originating from not the destination domain.
The email address of the recipient is
test.user1@receivingdomain.com but I dont understand in error message why it put the originating domain instead of the destination domain.
Looking at the contact properties of I can see only this line in the email tab
SMTP:test.user1@receivingdomain.com
The exchange trust is between Exchange 2010 and Exchange 2013.
I don't know if someone else has seen this.
