Microsoft recently changed the name of Office 365 apps to Microsoft 365 apps. I will be using a mix of both the names in this post. Before getting into details of supported versions of Office 365 apps, let’s go through the details of support scenarios and channels of Office 365 apps.

Microsoft 365 Apps Updates

There are two types of updates available for Office 365 and that is similar to Windows 10 update cycles.

  • Quality Updates – The Microsoft 365 Apps quality updates are monthly security (2nd Tuesday) & other quality updates.

There are four (4) update channels available for Office 365 apps. These channels are mainly to define the frequency of feature updates. All the update channels provide quality updates as well.

Version vs Build Numbers

The version & build numbers of Microsoft 365 apps (a.k.a Office 365 apps) are a bit confusing for me. Let’s try to understand it before checking the supported versions.

Let’s try to check Windows 10 version details. I explained Windows 10 Major Minor Build Rev | Where Can I Get Details in another blog post.

Office 365 App build number of 2008 = 16.0.13127.20408. The 2008 version of the Office 365 app is not supported anymore.

Office 365 Apps 👉👉 major.minor.build.rev = 16.0.13127.20408

  • Major – 16
  • Minor -0
  • Build 13127 (build number for version 2008)
  • Rev – 20408

NOTE! – As per my understanding, the rev version is updated with quality updates. The build version is updated with every feature update.

Supported Versions

Microsoft 365 Apps support is based on the version numbers. It’s also important to note that each version number has a unique build number. The build number is the one that can help you to create a report with a list of unsupported devices.

For example 👉 Build 13127 (build number for version 2008).
