Moving from EX 2007 to 2010 and want to know if it is ok to move the OAB generation server to 2010 now? users are still on EX 2007.

Hiya, Yes you can move OAB Generation to Exchange 2010 servers and also add OAB Distribution on Exchange 2010 at the same time as transitioning Client Access to 2010. SteveSteve Goodman Check out my Blog for more Exchange info or find me on Twitter

I'm not sure that helps me. Is it OK to move the generation server to 2010 while I still have alot of users on the EX 2007 server and they will probably be there for a few months.
