What kind of connector do you have for the two servers to talk to each other? You could setup an internet mail connector between both servers for communication. Other than that I would check the addressing between the two. Sounds like what is being delivered is not what the receiving server is expecting. Can you send email from the 2k server to the 5.5 server? Mike
-----Original Message----- From: Leo [mailto:[EMAIL PROTECTED]] Sent: Monday, May 13, 2002 4:42 PM To: Exchange Discussions Subject: Why is recipient name unrecognised? We have an exchange 200 server (sp2) on win2k (sp2) on Win2k domain A and an exchange 5.5 (sp4) on windows nt4 (sp6) on NT domain B. Both servers are in the same site/org. When an exchange 5.5 recipient sends email to an exchange 2000 recipient he gets an ndr stating recipient name is not recognised. When I look in the tracking logs it says message message submitted, \\exchange2000servername\trackinglogs\trackinglogddmmyy.log not found. Network name not recognised?? There is a two way trust between these domains and tracking is switched on. Any troubleshooting tips? Thanks folks.
