Customer has Exchange 2003 and wants to do a full migration to O365, probably using the Exchange 2010 Hybrid model. Does the Hybrid Key allow us to temporarily use a full Exchange 2010 server (CAS/HUB/MBX) to do a quick migration to 2010 first and then
move to O365? Or does it not allow the MBX role to be installed?
