Title: Error message: A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator.

Pls Help.
I have two Exchange Servers 2003 SP2.
There is One Domain on two sites.
From yesterday i cant send email beetwen servers, after 12 hours i get this error:
"A configuration error in the e-mail system caused the message to bounce between two servers or to be forwarded between two recipients. Contact your administrator"
I have cheked connectivity - no problem (IPVPN 512kb/s)
I have cheked SMTP connectors - there is no changes.
Routing Group Connectors - there is no changes.

One of servers is a new one.
A month ago i replaced old exchange server with new one, i moved mailboxes.And it worked good one month.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

first, enable the message tracking on both servers. Increase the diagnostic logging on MSExchangeTransport on both servers to maximum. Try to send a test message and track the message. check the application log. It might help you identify the problem here.
I would first run ExBPA on one of the servers and see what has been recently changed and see if this tool suggests something. (Download available on www.microsoft.com)

There are two objects with the same email address.  

Either somebdoy has configured a contact or a mail enabled public folder with the same email address, or you may be having a problem with replication with another server, or two mailboxes have been configured with the same email address.

Becuase I have six servers in my area, and I replicate with another country, I often see issues when replication occurs, and I can site some of those becuase it puts a string of numbers after the user name.  The multiple servers, also gives us a good environment for duplicates to happen all too often.
Check also if there is a similar scenario like this. User A's emails are forwarded to User B. User B's emails are forwarded to User A. The server is unable to decide where to send the emails to causing it to bounce between two recipients. If you do forward another users emails when someone goes on leave, there is a chance that this may happen.
Has Powershell sent you back into the Stone Age?

If managing Active Directory using Windows Powershell® is making you feel like you stepped back in time, you are not alone.  For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why.

Good One!!

We see this a lot.  Exchange only forwards it once tho.  Then it detects a loop and the non-delivery or error report says something about it unable to forward the mail becuase of a loop.

Now we just need to get our users to understand "never ending loop."  (high degree of frustration of course)

Thanks to everyone.
The problem was resolved by:
1. In the properties of routing connecctors i selected option "Any local server can send email over this connector"
2. In the properties of SMTP VS i changed from "All Unassigned" to current IP adress.
For now it is working properly.
