Hi.
Looking over our Office 365 reports I am seeing very large (>25K/day) spikes in inbound spam categorised as IP Blocked.
Our inbound spam is otherwise at relatively low levels, a few hundred messages are blocked a day by content filtering.
I can't see any way of getting more information about what's being blocked.
Since Microsoft seem to be blocking it effectively; is it something I need to worry about at all?
Or is this actually completely normal for Office 365?
Many thanks, Martin
