Why not just create a test policy and scope it to a few pilot users to see how it will effect you? I assume you are talking about creating a policy for Safe Links, Safe Attachments and/or Anti-malware? You can do this pretty easily here . Link above just takes you to: Microsoft 365 Defender>Policies & Rules>Threat Policies>Anti-Malware. For Safe Attachments and Safe Links policies, just step back one and you'll find it in the Policies Section in Threat Policies area here . Think it's the Safe Attachments that you mean though, correct? The one I did in my Azure lab is scoped to just me, but when I did this at work I created a Group, added some pilot users and then scoped to that to test when we did this. Probably best to scope any policy to some pilot group first rather than globally. More on reddit.com

r/Office365 on Reddit: Your Thoughts on MS Defender for Office 365 (Plan 2)?
March 15, 2024 -
We are using the above plan with the strictest preset policy and to be honest I'm not overly impressed with the security.
ATP in general seems like it takes hours to remove malicious links from emails which defeats the purpose.
Doesn't Scan Display Name so I have to create Flow Rules to cover that.
I have to create various other Flow Rules to cover things it misses frequently.
Phishing Training Videos are horrendous.
Seeing how it's $5/user I'm thinking about making the jump to proof point. Does anyone else have similar experiences?

Like everything in the Microsoft stack… it’s “fine”. It does the job well enough, however it’s not the best of bread. It does however integrate fantastically with the other Microsoft suite products if you have them, and does an excellent job of giving full visibility of end to end security when you do.
