Looking for Recommendations on Learning Microsoft 365 Business Premium

Microsoft 365 Business Premium has some really great Defender features, but you should start with the basics. Set up Universal Tenant Restrictions, conditional access policies, and then move on to the Defender Baselines. If you're using Entra Enrollment with Windows Hello, that's a solid step too.

Honestly, my advice is to just dive in and start deploying it—everyone else does! You can figure things out as you go. Just make sure you have a test environment so you're not risking anything in production.

I feel like the process usually goes like this: try to implement everything, get completely overwhelmed, and then reach out to Microsoft support who will probably just give some generic answers. After spending hours on forums like this one, you'll end up being the expert you were originally looking for!

For hardening your environment, grab the CIS benchmarks for Microsoft 365. They provide excellent guidance and can help you set everything up securely.

Honestly, have you checked out Microsoft's own documentation? They have great learning paths that could help you without needing to sign up for a course. Start here: https://learn.microsoft.com/en-us/microsoft-365/business-premium/?view=o365-worldwide
