I just rolled out exchange 2010 and am using outlook 2007. I need to be able to edit phone numbers in the GAL from outlook. Where do I add permissions to do this and add custom fields?

You can not modify it from GAL. You need to use ADUC or EMC for doing so. You can add yourself or the intended people into Exchange Recipient Management Group.Milind Naphade | MCTS:M (Exchange 2007 and 2010) | http://www.msexchangegeek.com

Have you looked at Gal Mod? http://support.microsoft.com/?kbid=272198Mark Morowczynski|MCT| MCSE 2003:Messaging, Security|MCITP:EMA 2K7,EDA Win 7,ES,SA,EA|MCTS:Windows Mobile Admin|Security+|http://almostdailytech.com

Hi, In Exchange 2010, you can do that in ECP, ADUC or EMC. It's not available in Outlook. Thanks Allen

what do I need to do?

Hi, In EMC, ADUC or ECP, you can open the user and edit it. Input the value based your need. Thanks Allen
