Distribution List Recipients Receive 2 or 3 copies of an email
Posted on 2006-07-17
We have recently set up a distribution list in our Exchange Server. When we sent an email to it some but not all get mutiple copies. Some get 2 and some get 3. Some might get more than that but I am not sure about it.
Here is the detail.
Config :- Exchange 2003 Enterprise SP1, Windows 2000 Native Domain, Outlook 2003 (internal Clients), Single Site / Domain.
We have a Global Distribution object. We have set up 78 Contact objects with email addresses that are external to our Exchange Server and 1 mailbox on our Exchange Server.
The addresses external to our Exchange Server are a wide mix of addreses but there are a few going to the same company and a few going to hotmail even.
An email is sent from an external mailbox to the Distribution list which then sends it to everyone. It is difficult to do more testing as I do not want to Spam the recipients.
Even the Hotmail users got multiple copies.
