I have just migrated my mailboxes over from exchange 5.5 to exchange 2003, and i see my messages in the MTA X400 queue, but the name of the server is the old server.

the messages in the x400 are slowly building up, but i see them decreasing once in a while, but increasing faster than decreasing

shouldn't messges be going out through the smtp protocol?

Hi,

The X400 queue is used for internal mail delivery. I would first try to mail something to your colleguea within the building and see if it gets there fast enough. If so, then i wouldn't worry to much about it and wait for a day or so to see if the problem persist, if so, please post and we will try to find a solution..

Hi,
mail goes to and from within the corporation fairly fast.

i think i forgot to mention that the x400 that the queues with the messages stuck in them had the name of the exchange5.5 server, which is about to be taken offline, but not sure why the queue gets filled up and decreases a little then fills again.

seems like it's doing something with some of the mail.

No idea either, normally this should not be happening.. You can stop the Exchange 5.5 services and see what happens.. I would keep the 5.5 server at hand if something goes awire (which i guess you figured out...)

Strange.. I'm out.. Should be seeing this to know what's wrong... I'm afraid i'm lost. Only thing i can think of is to reboot the Exchange 2003 server and see what happens (or stop and start all Exchange services)..

It could be that some users have contacts in their address books that have the X400 address of the recipient as opposed to the smtp address and when they send the message to that user it defaults to that X400.  I'm not sure how the X400 address gets in the contact info, but i have seen it here after moving a user to another server some people start getting ndr's and that is usually what we find.

If you select the user from the GAL, then everything will be fine.
 
The reason you could be seeing the queue decrease and then increase is the messages are probably timing out after x hours, etc and sending back an NDR to your user.  

If you don't have any users on the Exchange 5.5 server, then taking it offline should not cause any problems as long as you follow the Microsoft KB article for taking the first server in a site off-line.

I do beleive all mails are "gone" back to the sender with an NDR. Maybe these are the last things the 5.5 server wanted to do.. ;)

Hi,

I don't think i agree, in my first post i said

>>I would first try to mail something to your colleguea within the building and see if it gets there fast enough. If so, then i wouldn't worry to much about it and wait for a day or so to see if the problem persist<<

And as posted bij b8con, the problem just fixed itself. Maybe the answer wasn't quite right, but my remark was in the right direction... So i do believe i added some usable info. If b8con disagrees, i would be happy to hear it..

well, i think it did fix itself, but after 2 weeks i see nothing in the queues, but there was something i did change, which were the metrics for the protocols, i changed X400 protocols to a higher metric say (3) and left the SMTP metrics as 1, but since you guys helped i guess i'll give you guys the points.

oh one more thing, the different Global address book had nothing to do with which protocol it used, no matter which address book i sent the emails to on the list, they would go through smtp.
