I'm working on testing/upgrading to Exch 2007. I ran the exchange best practices analyzer tool on my current production environment and it came back with a warning "Policy change required' that referenced the link below. http://technet.microsoft.com/en-us/library/aa998426.aspx We are currently at an AD level of 2000 mixed which I am also working on changing to native and then 2003. This is the current value shown in ADSIEdit for "Mailbox Enable User". (|(&(objectCategory=person)(objectClass=user)(mailnickname=*)(msExchHomeServerName=*))(&(objectCategory=person)(objectClass=user)(mailnickname=*)(homeMdb=*))(&(objectCategory=person)(objectClass=user)(mailnickname=*)(homeMta=*))) Am I correct in assuming that if I take no action any "NEW" users after the switch will be re-homed? Do I need to make this change? I spoke with another companies admin and their value is the same as mine but are at AD 2003 native with no re-homing issues. Thanks

Has anyone seen/had experience with this?
