Hello 1 .- I currently have configured on an Exchange 2003 SP2 the @domain.com and all the email accounts of users discharge. Now I need to add @domain.org and update 90% of the users email account with these domain , and 10% date of the users email account with @domain.com. It is 250 users. As I do? 2 .- I have a folder in all mailboxes called SPAM that I create a old antivirus. I somehow delete all mailboxes at once? Thank you.

1.You will have to create custom Recpt Policy for @domain.org and make this as primary. and create some AD filters for rest 10% users to stamp with @domain.com Refer below Implementing Custom Recipient Policies 2. Yes can use the Exmerge to achieve the same. http://support.microsoft.com/kb/328202 Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|
