Worried about spam emails hitting your mailboxes? It is better to avoid this woe rather than
dealing with it later. You can create transport rules to block emails containing certain phrases
or sentences like "This is an advertisement", "You receive this email", "Click to unsubscribe", etc
which are most likely to be present in spam emails.
You have figured out how to block majority of spam emails in. But how do you know that you
have done it right? You need a less intrusive way to check the messages filtered by the transport
rule you have created, in your entire organization. This is where O365 Manager Plus comes
handy.

on messages filtered by transport rules. With this report you can get information on,
