Recipient Policy cannot be created on OU basis. You can either use AD attributes such as Office Description or Custom Attributes 1 t0 15 and then create policy to stamp mailboxes with these attributes See Below http://exchangepedia.com/blog/2005/09/how-to-create-recipient-policy-based.html http://msexchangeteam.com/archive/2006/11/16/431531.aspx Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

Yes. You can either use AD attributes such as Office Description or Custom Attributes and then create policy to stamp mailboxes with these attributes in Exchange 2007.And if yourexchange 2003mailbox store is arrangewith OU.like One OU,one mailbox store.Then when you create a recipient policy, you can modify the "filter rule" through "store" tab.Frank Wang
