HELP BIG Problem

[yarym]

Ok. I added 2003 Exchange to my 5.5 ORG. I moved several users to Exchange 2003 for testing purposes. Here is the problem. I can't send mail to some, but can send mail to others on the 5.5 server. I get an undeliverable response saying that "The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again." I don't understand why mail for some users goes through and for others it does not. PLEASE HELP.

Ok. It seems to me that for some reason, the messages are trying to be send using the x400 connector(which I dont have). I found in the eventlog that the message is being redirected. This is the message:

A non-delivery report (reason code unable-to-transfer and diagnostic code unrecognised-OR-name) is being generated for message C=US;A= ;P=Linzer Products;L=MAILNY-050427232141Z-13. It was originally destined for DN:CN=MARKS,CN=RECIPIENTS,OU=LIER,O=LIER§ (recipient number 1), and was to be redirected to . [MTA DISP:RESULT 16 136] (12)

Someone please help.

Yari if you get a NDL error it should have a code and
the server who returns it. I asume it is 5.1.1 and your
new server returns this code.
Your error description is without this information a guess,
but I think you try to mail to users outsite the new
server who has the same email domain name. In this case
the server don't have this name and will return it as
undeliverable.
Check under exchange manager, admin groups, servers,
your server, protocols and open SMTP. Right click the
virtual SMTP server and under messages see what you have in
forward all mail with unresolved recipients to host.
Hope this will help.

Hi! I'm sorry, but your answer does not really make sense to me. I have users on 2003 and 5.5 servers. They both belong to same org and even same site. When a user on 2003 sends mail to user on 5.5 I get an NDR "The e-mail address could not be found. Perhaps the recipient moved to a different e-mail organization, or there was a mistake in the address. Check the address and try again." Also, whats really confusing, is that users on 2003 can send mail to some users on 5.5 with no problem, but for other users they get an NDR. I don't see any differences between the users.

Enable tracking and check the results, as well turn on full logging to follow mail flow.

From here, we cannot 'see' what is going on and as there are no clear errors or such, we would be guessing.

If your logs or traces don't help, get someone in to check it out.

It sounds like there is something wrong with the ADC. Verify that all recipients show up in AD and in the Exch 5.5 directory. Also, you should have done a DS/IS consistency adjuster on the 5.5 side before installing the ADC.

MY ADC is working fine. I ran verify and it came out fine. Turning up looging, I get the error that I mentioned above in the second post and now I'm also getting another error: "The MTA was unable to route to recipient ...." These are x400 messages. Is mail in the same site suppose to use x400? Also, since my mailbox is on the 2003 server, I can click on To in outlook and I get a full list of people. If I click on properties, their email address shows up.

It is a 5.5.1 and the server new 2003 is sending your the NDR? I think yes. Let me know how both servers are configured? Are they both domain controllers and replicating each other or do you have the 2003 configured as a standalone server for testing purposes.
Do you see all users in the global list on 2003, also the users who's mail bounced back?
Also do you have a single domain? Is your 5.5 running on NT4 or Win2000? Hope you still have 2003 in mixed mode or
2000 mode?
Let me know and I might be able to help you out, I had simular problems, but had to set forwarding to users who are not users on this server as I described earlier.

Exchange 5.5 is running on Windows 2000 and Exchange 2003 is running on 2003. Both severs are just stand alone servers. I can see all the users in my GAL. This is a single domain and all users are in one site. Exchange 2003 is in mixed mode. Right now I'm in the process of rebuilding the whole Exchange 2003 from scratch in hopes that its the usuall microsoft glitch.

Hope that will fix your problems.
Did you use the pop3 connector?
Did you use mail delivering by DNS or forwarding?
Remember than that
if user1@mydomain.com send mail to user2@mydomain.com and
user2 is reading his mail from the 5.5 server he will
not receive his mail and user1 will receive a NDR.
This is because exchange 2003 doesn't has user2 in his
userlist and has no idea where to send. This because they
both belong to mydomain.com. Mail to all other domain names will be forwarded, but not mail with the same domain name.
This is by default, you have to tell exchange 2003 to forward mail from unknown users in the SMTP properties.
Hope this will help you understanding how the mail works.

Sorry, i don't understand. Both of these servers are in one site. When installing 2003, I joined the 5.5 Org. Also, when my mailbox is moved, I can see all users in my GAL. Here is a thought though. I think the problem is in the way my domain is setup and Active Directory. Looking at the event log, when message bouces back, this is logged:

A non-delivery report (reason code unable-to-transfer and diagnostic code unrecognised-OR-name) is being generated for message C=US;A= ;P=Linzer Products;L=MAILNY-050429175517Z-9. It was originally destined for DN:CN=ZLO,CN=RECIPIENTS,OU=LINZER,O=LINZER PRODUCTS§ (recipient number 1), and was to be redirected to . [MTA DISP:RESULT 16 136] (12)


Now, looking at the destination address, my domain name is Linzer, but that user is not in the Recipients container. Does that matter?

 

[bennetje]

yari I think it matter. I remember now there was a microsft article about this problem. I still think that what they descriped there is your problem.
It fixed my problem, so check it out. Maybe Microsofts description is better to understand than what I like to explain you. See article 300681 or use this link

Hope that will help for you, good luck

[yarym]

well, the article you are refering to is for pop3 accounts, plus, they are talking about if you have 2 seperate exchange Organizations for the same domain name. That is not the case here. Also, I did try to add the server anyway, but it did not work.

 

[bennetje]

Now I don't know. Two messages ago in the event log you had an O and P as Linzer Products in your AD.
Not sure but it might be in your AD as you mentioned earlier that you suspect the problem there.
Maybe not a bad idea to rebuild everything from scratch after all the changes you have made.
