The objectives for MS-100 has recently been updated, and while it is mostly a minor update focused on correcting grammatical errors, a few things have changed or been moved around. You will notice most of these changes in the Microsoft 365 apps and Teams sections, so let’s start there before looking at a couple of other changes.

The major change I noticed in the Microsoft 365 apps deployment section was the switch from using “Microsoft 365 Apps for enterprise” to “Microsoft 365 Apps” where it had been used previously. This is a welcome change, because it meant that instead of raising concerns about “for enterprise”, and did that explicitly mean the “for business” option wasn’t included, instead the focus is just on managing and deploying either of them, which does mean that you might need to dig in a bit to the differences. Don’t worry about the minutiae when it comes to feature differences, instead focus on some of the basics like being able to control more settings in the enterprise edition versus the business edition, using technologies like Group Policy or config.office.com for example.

The Teams section of the exam has also been expanded, so make sure you have an understanding of allowing external users and guests into your tenant via Azure Active Directory, and then how Teams and SharePoint permissions determine what external users and guests are able to do with those permissions. This is an example of more of the Office 365 workload knowledge creeping into this exam as it had previously with the addition of Power Platform objectives, with the same trend being exhibited in MS-101.

An entire section objective has been removed – “Configure Microsoft 365 tenancy and subscription” – but much of what was in there was already covered in other objectives, and realistically should be base level knowledge that anyone planning on taking this exam should have. Removing something like “evaluate Microsoft 365 for your organization” is something that has become less relevant over time because that evaluation has already taken place in many organizations.
