Intune Plan for Change: Microsoft 365 apps version 16.44 and higher to install on macOS 10.14 and higher

Starting with version 16.44, Microsoft 365 apps are supported only on macOS 10.14 and higher. In March, Microsoft Endpoint Manager will deploy Microsoft 365 apps to only macOS 10.14 and higher.

How this will affect your organization:

Given that Microsoft 365 has ended support for macOS 10.13.x in November 2020 (MC223176) you may not be affected; you have likely updated your OS or devices. You will not be impacted if you are currently managing macOS 10.14 or higher devices. However, if you are currently managing macOS 10.13.x devices that have Microsoft 365 apps installed, these app installations can be updated up to version 16.43 using Microsoft Auto Update. But Microsoft 365 apps are no longer supported on macOS 10.13.x and will not receive any security updates or bug fixes in the future. It is recommended that these devices are upgraded to macOS 10.14 or higher to install the latest Microsoft 365 apps.

What you need to do to prepare:

If you are currently managing macOS 10.14 or higher devices, no action is required. Older versions of Microsoft 365 apps can be manually added to the Microsoft Endpoint Manager Admin center per the documentation here.
