Exchange 2010 SP3
is it practical or even advisable to place distributed Exchange servers in branch offices with a view of speeding up the OAB updates (we are cached mode users)?
my thinking is with a centralized Exchange servers, everyone from HO to remote branch offices are vying for attention when it comes to OAB updates. if I distribute the Exchange servers, then the main Exchange servers need only talk to one Exchange server per branch as opposed to all users per branch.
