Good day, while moving several mailboxs from Exchange server 2003 to another Exchange server 2003 , some of the mailboxes were moved & the others didn't . After that I realized that the calendar & tasks of a specific user (that wasn't moved to the new server and made failure report ) were moved to another user !! this is a strange issue . Does anyone have an explanation for what is happening !! because it is dangerous if items were moved to other users !! Regards Elias Dayeh
