Hello spiceheads,
I am migrating from Office 2007 to Office 365 Pro Plus (just the client, no hosted exchange, etc). I have Server 2008 R2 domain/forest functional levels and a local Exchange 2010 SP1 server and want to use dirsync to synchronize my user information so that users don't have to sign in with different credentials to install/activate office.
I was reviewing the information regarding the preparation for directory sync from the link below

My question has to do with the "Review UPN Requirements" portion. Specifically with the publicly routable domain. My AD domain is abc.local so I would need to add an alternative UPN suffix, say abc.com. Does this require me to have the .com version registered or is it that I just need to have the TLD?
