How to deploy M365 Companion app through Intune

I’ve run into this before—deploying the M365 Companion app via Intune isn’t always straightforward with a raw Win32 package. A couple of things to check:

Make sure you’ve wrapped the installer with the IntuneWinAppUtil tool and configured detection rules properly (e.g., registry key or installed file path) so Intune knows when the app is installed.

The /quiet switch is correct, but you may also want to add /norestart to avoid unexpected reboots.

Run the install under system context in Intune (user context can fail silently).

Double-check that your app requirements (OS version, architecture) match the devices.

If it still fails, check the Intune Management Extension logs (IntuneManagementExtension.log) for more detail—it usually points out whether it’s a detection or execution issue.

Some admins also recommend packaging it as a line-of-business (LOB) app if the MSI wrapper is available, since it can be easier than Win32.
