How to Enable Additional Office 365 Email Filtering Settings

By November 1, 2016Microsoft, Office 365

Office 365 has many features you can enable to help reduce additional spam and malware. Below are a few of the higher-level Office 365 email filtering settings that can compliment your existing email filtering solution.

In your Office 365 Console, open the “Exchange admin center,” select “protection,” “malware filter” and then edit (click the pencil icon) your Default rule as shown below:

The rule above is a more severe setting that will fully delete any email with known potential malware-type extensions. You can, however, make it less austere by using the other settings to strip the attachment instead and alert the reciever that is was removed. This way the intended recipient will know to follow up if the filtering perchance stopped a legitimate file.

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

In the same “protection” section under “Exchange admin center,” select “connection filter” and “enable safe list” to allow Office 365 known safe senders as shown below:Office 365 Email Filtering

In the same “spam filter” section, select “international spam” and select every country and language you DO NOT want to receive email from. If you are a business in the midwest USA and have no international clients or vendors nor want any, then lock it down to English and USA as shown below:

Please note that we don’t recommend this be your entire spam filtering solution. This is just another built-in safeguard we like to enable on top of additional spam filtering.
