Hi, I need to move 511 distribution group to a newly created address book only for these distribution group so is there an easy way to do this as there are total of more then 700 distribution groups in the list. Please advice.

Please provide more infromation about the Exchange version you are using. If you are running 2007/2010 there are poswershell commands you can use to modify address lists and that might help you, so which version are you running?Martin Sundstrm | Microsoft Certified Trainer | MCITP: Enterprise Messaging Administrator 2007/2010 | http://msundis.wordpress.com

we are using exchange 2007

Then you should be able to use a filter that matches your preferences, see if you find what you need here: http://technet.microsoft.com/en-us/library/bb123718(EXCHG.80).aspx To create a address list that includes all distribution groups try this: New-AddressList -Name "test2" -RecipientFilter {(RecipientType -eq "MailUniversalDistributionGroup")} The command can be altered and more recipient filter conditions can be added if you want to narrow the results.Martin Sundstrm | Microsoft Certified Trainer | MCITP: Enterprise Messaging Administrator 2007/2010 | http://msundis.wordpress.com
