I work for a school district, whose students are transferring over from Microsoft's Live@edu to office 365. I have been told by the Microsoft people in charge of this conversion that it would be best for me to have the schema update for Exchange 2010 sp2, in place.
My domain is 2003 functional. And my staff currently uses, exchange 2003 sp2.
My question is, would installing the schema updates have any adverse effect on my exchange 2003 users ?
