Office 365 increased email filtering

With Office 365 there are many features you can enable to reduce additional spam and malware. Below are a few of the higher level settings that can compliment your existing email filtering. On your Office 365 Console open the “Exchange Admin Center” select “protection”, select “malware filter” and edit (pencil) your Default rule as shown below:

The rule above is a more severe setting that deletes the full email with known potential malware type extensions. You can however make it more end user admin friendly by using the other settings to strip the attachment instead and alert the reciever that is was removed.

Note: Don’t forget to hit “Save” in the bottom right hand corner

In the same “protection” section select “connection filter” and “enable safe list” to allow Office 365 known safe senders as shown below:
