Hi All, I just migrated from Exchange 2003 to Exchange 2007.Everything went apparently ok. I moved all the mailboxes from the old 2003 to the new 2007 and it worked smoothly. Just 2 issues : a) The new users created from the 2007 GUI are not able to open the "Out of the office rule" . Users moved from the old 2003 are not affected. b) Users moved from the 2003 are not able to open the resource scheduling in the calendar options. New users created from the 2007 GUI are not affected. Any help will be appreciated. Regards, Eric.
