Exchange error delivering mail: 550 5.2.0 RESOLVER.CON.NoTarget

All users in organization "lb.no" is unable to deliver mail to ONE person in orgnization "lk.no".
All users in organization "lb.no" is able to deliver mail to all other persons in orgnization "lk.no".
Both organizations have Exchange 2007.

Some of the error message is in norwegian, but I hope you understand the problem:

If this addressee is in fact a true Contact, I would suggest deleting the Contact from Active Directory and re-creating it.

I'm not shure if he is created as a Contact in AD. I'll check it out.

The contact in exchange org "lb.no" was deleted and re-created. Still no luck sending e-mail to this contact. There might be a delay before seeing any result because of address list updating/synchronizing.

Simplify Active Directory Administration

Administration of Active Directory does not have to be hard.  Too often what should be a simple task is made more difficult than it needs to be.The solution?  Hyena from SystemTools Software.  With ease-of-use as well as powerful importing and bulk updating capabilities.

I do not know why "lb.no" creates contacts in AD. (Strange policy if you ask me.) The IT manager in that organization has reported problem with the company hosting their exchange servers.

Old thread, but i just got this problem after a migration to office365.
The migration set some weird options on the old exchangeserver.

For me it was that the "External E-mail Address" was gone from the Mail Contact in the Exchange server. So just had to edit the contacts and change the smtp-address to be external.
