2003 SBS Server, Exchange 2003. I have a small company of around 50 staff and 300 associates(real esate). The Active Directory is assembled as so: Each staff member is set up as a user account, each associate is setup as a contact and company Distribution Groups are "universal" (there is only one domain).
As new associate accounts are setup, the SMTP is modified to reflect thier 3rd party email address. They are then entered into one of the distribution groups.
Problem: When an email is sent to a distribution group, the individuals listed as contacts will receive the email anywhere from 5-11 times. The users on the domain (checking through Outlook) do not receive duplicates.
I have rebuilt the dist. groups, limited the number of contacts in them....still happeniing. I have had this problem for over a month now and I really need a cure. I am even willing to let someone RDP into the server to take a look Exchange.
