Hello, I have an Windows 2008\Exchange 2010 environment and I would like to update all the users "address and phone" attribute so when I view GAL in Outlook 2010 I can see everyone information. Basicially I will be using GAL as an directory. Is there a way to update all my users at once instead of doing it manually? Thanks

You can use AD Modify tool to change it. But you need to create script for it. http://www.activedir.org/Articles/tabid/54/articleType/ArticleView/articleId/45/Default.aspx I will advise you to post same question in active directry forum so someone can give script detail to you.Anil MCC 2011,ITIL V3,MCSA 2003,MCTS 2010, My Blog : http://messagingschool.wordpress.com

Why not leverage the ECP 2010 and have your users enter the basic contact information and keep it up to date. Addresses and phone number might change. Exchange 2010 OWA - Exchange Control Panel http://www.exchangeinbox.com/article.aspx?i=145MCTS: Messaging | MCSE: S+M

Agreed with both of them, you have two options here.Gulab | MCITP: Exchange 2010-2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.Blogspot.com
