I have an error when sending mail from 2010 to 2003 coexistence:
error 550 4.4.7 queue expired; message expired
This is the version I use to test
Ex2003 | v6.5 Build 7638.2 SP2 | 6.5.6500.0
Ex2010 | v14.3 Build 123.4 SP3 | 8.0.535.0
Testing to upgrade Exchange 2003 to 2010. Reference Exchange upgrade guide
There are problems with one of the RGC (Routing Group Manager) connectors, the connector was created again but the same problem continues.
These are the tests that were carried out to send mail:
source | destiny | status mail |
---|---|---|
Ex2003 | External | OK |
Ex2003 | Ex2010 | OK |
Ex2010 | Ex2003 | does not send |
Ex2010 | External | OK |
Reviewing the logs and trying to find any error messages
- Event Viewer no error.
- Send queue, there is no error (it is pending).
- Exchange log, shows error that it did not send 4.4.7 relay.
Checking the possible errors caused by NDR 4.4.7 (MX, DNS, AD, NSLookup) is fine.
- How can I test the connection between the Exchange Servers?.
- What logs in ASDEdit should I check if the logs are okay?.
- What other reason can cause error 550 4.4.7 queue expired message expired?

Since the exchange 2003 and exchange 2010 are not support, you'd better migrate all exchange 2003 mailboxes to exchange 2010 then go to exchange 2016/2019 or exchange online. Detailed steps for you reference: how to migrate exchange 2003 to 2016 including active directory renaming please help
We want to migrate Exchange 2003 to 2019, with exchange 2010 as a temporary bridge.
Thanks for the info Joy Zhang, I was reading all the documentation, I'm done running the tests and I'll let you know how it went.
Thanks for the advice Pimp Juice IT, looking for information to test connectors between exchanges.
The curious thing that I saw in the logs, the same EX2010 closes the connection and doing the same with telnet sends the mail without problem to EX2003.
I am looking for information that can cause the connection to close in the connector.
Send Mail From Exchange 2010 to Exchange 2003
Checking the exchange 2010 logs, in connectivity logging there is an error.
Looking for the error it shows in logs.
The error was found and it was solved with the following guide of the error 451 5.7.3.
Thank you very much for the advice, I hope this helps you to update your mail server.
