Hi there.
We need some clarification regarding EOP.
If we take a look on this site: http://technet.microsoft.com/en-us/library/jj723119(v=exchg.150).aspx
we see this sentence: "Microsoft Exchange Online Protection (EOP) is a cloud-based email filtering service "
Does this mean that your business mail is being filtered outside your on-premises Exchange servers, or is it filtered on the Exchange server?
