Learn How to Configure Defender for Office 365 for Maximum Security

In this video, you will learn how to configure Defender for Office 365. Defender for Office 365 is Microsoft's own email security product. There are two ways to configure, an easy one and a harder one :-)

I'll walk you through the preset policies which can be enabled very easily and provide your business with some protection.

I will also show you how to create your own:

► Anti-spam policy
► Anti-phishing policy
► Anti-malware policy
► Safe attachments policy

Super interesting video, it has been very helpful, thank you very much.

We don't like users releasing their own emails from quarantine or their emails going into junk mail. We perform a quarantine sweep twice a day and if there is something a user wants released, we let them send a request to have it released.

Hi @Jonathan Edwards, Thanks for making this video. It was very helpful, and I learnt a lot. Thanks again. Would like to learn more about M365 Defender MDO, MDE, MDI and MDApps.

[CliffordJones-ivdo]

What a great, easy to understand video.

[sails]

Great guidance, thank you! Are you planning on doing something similar for DLP policies?

[fmalgapo]

So here’s a question: say you create your custom anti-phishing and anti-spam policies, what then becomes of the default anti-phishing and anti-spam policies? Does the custom at 0 weighted priority overrule the priority low default policies? I don’t see a way to turn off the default policies so that the custom policies don’t conflict with the default policies.
