Managing apps and software deployment through Microsoft Intune
Intune currently has no management control or insight over M365 app updates. All updates of M365 apps in this scenario happen per the built-in M365 apps functionality as detailed at https://learn.microsoft.com/en-us/deployoffice/overview-update-process-microsoft-365-apps.
We are in the design stages for some additional integration, but there is no commitment or timeline for this.
