Hey All- Is there any feature limitation of Hub Transport and CAS as it relates to Enterprise/Standard license???? Can I deploy HT and CAS with Standard licensing and still get all of the same features??? TIA

Hi, Check here:http://www.microsoft.com/exchange/2007/evaluation/features/ex_compare.mspxand here:http://www.microsoft.com/exchange/2007/evaluation/editions.mspxSF - MCITP:EMA, MCTS

Thanks. I've looked ta those pages and they don't seem to answer my question. Is there any difference in using Standard or Enterprise server licensing on Hub Transport and Client Access servers. I understand that CAL licenses enable different features, but I cant determine if this server licensing needs to be done one way or the other.

HI,Base on my knowledge there is no limitation for HUB and CAS server with Exchange 2007 Standard edition. But you have to select right Edition for your mailbox server because only exchange 2007 enterprise edition supports More storage groups, Databases(50) and SCC,CCR, Refer below URL for more information regarding feature differences =======================================================http://www.microsoft.com/exchange/2007/evaluation/editions.mspxRegardsChinthaka

I do not believe there is any loss in the Hub/CAS functionality in Ent vs. Std.Mailbox Servers are a different story though.SF - MCITP:EMA, MCTS
