Answer : Entourage Client on Snow Leopard connecting to Exchange.

As an FYI, you should have Exchange 2007 SP3 installed (skip SP2 as it requires special techniques and Exchange SP2 are cumulative), Windows Server 2008 SP2 and Small Business Server Update Rollup 4 and you'll find alot of other issues will go away (or not show if they haven't yet)
