Hi
We are planning to install SP3 to Exchange 2010. Currently we are doing the migration from 2003 to 2010 and migration of user accounts have not yet started. So is it recommended to install SP3 now or it can be installed at a later stage? Our AD domain functional level is 2003 and not yet upgraded to 2008 (in SP3 documentation it's mentioned as a supported environment)
