Exchange 2007 Enterprise CCR I'd like to create a new address list based on display name content i.e., *<location>, how do I use the Custom Attributes to do this?

Not sure what do you mean "On display name content" however the following method you can appy cutomer attributes: new-AddressList -Name 'Custom AddressList' -IncludedRecipients 'AllRecipients' -ConditionalCustomAttribute1 'NY' -Container '\' -DisplayName 'Custom AddressList' Aftre then update you address list: update-AddressList -Identity '\Custom AddressList'Best Rgds, Ashish | Unified Comunication | MCTS | MCITP | Please remember to select option "Propose As Answer" if solution work for you | My posts hold no assurances, no promises, and they measured no rights.

Thanks for your reply Ashish. When I try to create an address list the conditions have 3 defined and several custom attributes, can I define one of my own? Senario - we have several locations and we append the location to the users name in the display name field like this Doe, John - XYZ so based on this I'd like to create an address list that displays all XYZ I hope this makes sense?

I ran this and edited the NY to something use use but did not give me any different results than a standard address list.

please correct me, if i am wrong. Are you looking at create a address list where any user has XYZ string in DisplayName.Best Rgds, Ashish | Unified Comunication | MCTS | MCITP | Please remember to select option "Propose As Answer" if solution work for you | My posts hold no assurances, no promises, and they measured no rights.
