MS-900 Study Guide – Microsoft 365 Fundamentals

The MS-900 exam is the only exam needed to get the Microsoft 365 Fundamentals certification, and an optional exam in all the other Microsoft 365 Paths. This exam is designed for candidates looking to demonstrate foundational knowledge on the considerations and benefits of adopting cloud services in general and the Software as a Service (SaaS) cloud model. This exam will also cover knowledge of available options and benefits gained by implementing Microsoft 365 cloud service offerings.

In this study guide, I will share both free and paid options, whether books, video training or simply links to articles and blog posts. I will not share any dumps as those are against the Microsoft Terms of Service, and by using dumps, we decrease the value of our certifications.

Additional Tips

I think the best thing that you can do after reading this, or even meanwhile, is to open up an E3 or an E5 trial subscription, and try out everything that you read about. Only when you try it, you hit some bugs you really understand how it works in a real life scenario!

    Thanks Vlad

  • July 2, 2020 at 5:41 am

    Hi Vlad, I notice the skills measured have changed slightly to include different skills such as Dynamics 365 – just wondering if you’ll be doing an update?

    Thank you,

    • July 2, 2020 at 1:03 pm

      Hello Victor,

      I definetly plan to do an update! Been busy with some of the new exams, but updating all of them is on my to-do list!

  • July 9, 2020 at 12:30 pm

    Hi Vlad,

    I was wondering if you have any rough approximation as to when you might release an updated version of the MS 900 study guide?

    I see the exam material has been changed as of July 8th and I plan to begin studying for it next week.

    This is amazing work by the way, thank you very much!

    • July 10, 2020 at 11:09 am

      Hello Jake,

      Right now the plan is PL-900 / AZ-104 which should be done by end of month. Next up is updating the MS-900 and AZ-900 after!

  • July 21, 2020 at 8:12 pm

    Vlad how are you? Very cool name!!

    Was wondering, If I hustle each evening after work for about 3hrs for an MS900, how long would this take me

    • July 22, 2020 at 2:08 pm

      I think within a week or two you would be good to go! MS-900 is really a fundamentals level exam so 15-30h of hustle should be good enough!

  • July 22, 2020 at 5:33 pm

    Hey Vlad,

    Just watched 2 of your courses and so far enjoying it, regardless if the content of the exam has changed.

    To help me discover what I need to study in addition, and to compliment your 3 courses on Plural, can you point me in the right direction?


    • July 22, 2020 at 7:29 pm

      Hello Thomas,
      Here is the extra stuff I would reccomend studying:
      -Basics of Dynamics 365 / Power Platform (just know the different products inside)
      -The different deployment rings for Office ProPlus (M365 Apps) and Windows
      -The new names for different products (ex: Endpoint Configuration Manager
      -MyAnalytics / Workplace analytics

      Super glad you’re enjoyng the content so far! Updating the study guide first is on my to do list for next month!

  • July 23, 2020 at 8:28 pm

    Hi Vlad,
    Many thanks for all your courses and the great work you are doing for the community. Really awesome.
    I want to know where to start with my certification.
    My background is M365 beginner.

    • July 24, 2020 at 2:39 pm

      Hello Lilly,

      I would definetly start with the MS-900 exam, and after you can look in what part you want to specialize in, Modern Desktop (MD-*** series) , Teams (MS-700) or Exchange (MS-203). You can also learn the fundamentals of Power platform (PL-900) and/or Azure (AZ-900)

  • July 24, 2020 at 7:22 pm

    Thanks heaps Vlad!

  • July 25, 2020 at 4:08 pm

    Hi Vlad! Thank you for page! I passed the exam after revewing this page and the videos on PluralSight.

    Now that Ive passed the MS-900, what would be the next exam I can prepare for to build off the fundamentals I just learned?

    Thank you!

    • July 25, 2020 at 7:19 pm

      Hello Richard! Congratulations on passing the exam!

      Next steps would either be going for the fundamentals of other MS cloud products (AZ-900 for Azure / PL-900 for Power Platform). If you want to specialize into Microsoft 365 you need to choose either “Modern Desktop” (MD-100/101) , E-mail / Exchange (MS-203) , Microsoft Teams & Collab (MS-700) , Security (MS-500) , or Dev (MS-600). There are still some SharePoint exams (MS-300/301) but those are going away Aug 31st. Let me know if you have any other questions!

  • August 7, 2020 at 11:15 am

    Hey Vlad,

    Thank you for compiling all the topics that we need to study for this exam. Since the change of the exam, I noted your suggestions in the previous comments and the exam has Dynamics 365 questions.

    Best of luck in updating this and keep up the good work.

    • August 7, 2020 at 12:02 pm

      Hey Dawn!

      For full transparency right now I am kind of waiting for Microsoft Ignite as that’s where Microsoft usually announces major changes to Microsoft 365 certs/learning. Since that’s ~1 month away I want to see if there’s any major updates before refreshing all of it!

  • September 12, 2020 at 7:40 am

    Hi VLAD,
    appreciated your detailed topic list, i need to know that is there any course update by micorsoft in MS-900 or can i prepare this course with same material as you shared

  • October 2, 2020 at 3:45 am

    I have noticed in Microsoft.docs that names for Advanced Threat protection tools have been changed to “Microsoft Defender”.

    Microsoft 365 Defender is the new name for Microsoft Threat Protection. Additionally:

    Microsoft Defender for Endpoint is the new name for Microsoft Defender Advanced Threat Protection.
    Microsoft Defender for Office 365 is the new name for Office 365 Advanced Threat Protection.
    Microsoft Defender for Identity is the new name for Azure Advanced Threat Protection.

    Learn more. We’ll be updating our products and docs soon, so keep an eye out.
