For those of you who plan to get the Microsoft 365 Certified: Teamwork Administrator Associate and looking for materials to study, I have put together a study guide for the MS-300 and one for the MS-301 exams. They both contain a mix of free and premium sources, as well as books, video trainings, TechNet documentation, Office Support documents , blog posts and more!
Feel free to give me your opinion if anything can be improved in the future!
