If you get the same error then I'd say that the address isn't in the
directory you're using.

Try using LDP.exe and the ldap query
"proxyaddresses=smtp:userb(a)ab.com" and see if you find the user. Make
sure you query a GC in the same domain that your appliance does.

This newsgroup was supposed to be shut down by MS on June 1st. I'd
suggest that you ask this question in the TechNet forums that MS seems
to think are superior to newsgroups.

http://social.technet.microsoft.com/Forums/en-us/categories/

The software isn't tied to Exchange so you'd probably be better off
asking in a forum for Active Directory.

The user is not in our AD and this user is in company B. If user is not in
our AD, it should use SMTP connector for ab.com (SMTP sharing space) to route
users at company B(SMTP connector for ab.com -unathoriative are configured at
both company and check the box "allow relay to...")
When I trace the message, the appliance finished all checks and start to
deliver the message to our exchange server and failed with that error. Why
did exchange use the SMTP connector to route message to userB at company B?

Thank you.

Then you can't do recipient validation. This is what I meant when I
said that if you didn't have all the addresses in both directories
that you'd have to accept all mail sent to your ab.com domain.
Addresses that can't be resolved by the Exchange servers in Company A
would have to be sent to Company B (i.e. the smart host) and if they
couldn't be resolved there they'd have to be NDRed.

But you'd have to accept the message 1st. And as long as you're
validating that the recipient exists in YOUR directory you'll reject
all the addresses in ab.com that *don't* exist there.

Why *did* it? Or why did it *not*? It sounds like you're doing
recipient filtering on the Exchange server and not the appliance.

Human error:-) I thought that I made ab.com unarthoriative and it's
authortiative when I checked it today.

All are wroking fine now.

Thank you and have a nice weekend. Watch world cup games? and enjoy!
