Hi All,Is there a way of retrieving the date when a mailbox was migrated from Exchange 2003 => 2007?Thanx in advance.Dave

Hi Dave,Basically there are two ways...1. If you have archived event logs then you can scan it. When mailbox movement starts it generates an event id 1006 and when completes 1007 with source "Exchange Migration" on destination Exchange 2007 server.2. If it has not move to any other Exchange 2007 mailbox server then you can check the value of "PR_CREATION_TIME" in mailbox with MFCMapi because mailbox moves treated as a new mailbox creation on destination database. Check below thread for further detail about it.http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/44d89457-c9cf-4d42-bb88-88790e96baa8/Amit Tank | MVP - Exchange | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com
