Exchange Server Enterprise 2003 SP2 on Windows Server 2003 SP2.  Occasionally a user will report that a message received from an outside address will be received repeatedly, every hour or two.  When I do message tracking using the Exchange System Manager tools the results show the message being received once by the Exchange server, but the right side of the screen shows the usual list of events (submitted to advanced queuing, submitted to categorizer, queued for routing, queued for local delivery, delivered to e-mail address) repeated over and over about 10 times or more.  What would cause this, and what should I do to stop the repeated deliveries?  Thanks for any suggestions.

Hi,

I have seen somthing slightly like this before. I don't remember the exact solution but do remember it was something we got MS PSS involved in.

I would suggest you first run the Exchange Best Practise Analyser and see if that turns up anything obvious.  

If not, I would suggest you give PSS a call.

 

Cheers

Nathan

I just had this happen the other day. The e-mail said that it was being delivered but never did. The end user got a copy of it every hour. I looked at the message and it wasn't getting some kind of response back from the end users server to say that it got the message. I had to freeze the message from that domain and then wait a few hours (over night) and then unfreeze it and force it to connect and it worked. Something about the message was stuck either in our outgoing or their incoming and not allowing the mail to be released. This is only happened once but I am sure that it will happen again.

I think that it just never got the acknowledgement back from the end users server and so our server didn't know that it had been since. Smart server isn't it.
