Hi Can you please help me, How to Prevent Distribution List Expansion in exchange 2003.

Do you mean size of distribution list you want to prevent. You can do restriction in below manner. 1: You can hide user from DL 2: You can classify DL for seperate department users. 3: Restrict users to access DL Anil

On the exchange advanced tab, there is a setting for "Expansion Server" If you have a dedicated expansion server fo DLs, you can use the dropped down option there to select the server which you want to use. By default the setting is "Any server in the organisation" thanks ThiyaguThiyagu | MCTS/MCITP - Exchange 2007 | MCSE 2003[Messaging] | http://www.myExchangeWorld.com.
