Starting with Exchange 2007 and continuing with Exchange 2010, address lists, dynamic distribution groups, e-mail address policies, and global address lists can be customized with recipient filters that use OPATH filtering syntax.

Get-*cmdlets using the-Filterparameter:Get-Mailbox -Filter {Office -eq 'Sales'}In addition, we can use attribute filters to create distribution groups, e-mail address policies, and address lists using the
