I have Exchange 2007 Management Tools installed on a 64-bit Win2K8 box which is not an Exchange server. I have a few pre-existing users in AD for whom I would like to add Exchange 2003 mailboxes for.I was unsuccessful but can this be done - use Exchange 2007 Management Tools to add Exchange 2003 mailboxes? How about create Exchange 2003 User and Mailbox?Thanks.Anu AM

No, actually you should NOT use Exchange 2007 management tools to create Exchange 2003 mailbox, however you can edit or remove and manage those after creation with 2007 management tools.Find some thumb-rules or guidance in below article from MS Exchange Team while managing Exchange recipients inco-existence.Exchange Server 2007 and 2000/2003 systems management co-existencehttp://msexchangeteam.com/archive/2006/10/09/429135.aspxAnd here is the guidance to manage Exchange 2003 server related settings in coexistenceManaging Exchange 2003 Settings in a Coexistence Environmenthttp://technet.microsoft.com/en-us/library/aa995972.aspxAmit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
