When deploying Office 365 updates via SCCM, we noticed that the client machines are not actually receiving the update and in the dashboard from SCCM console they appear as Unmanaged.

Cause:

Office 365 update does not install on the client because OfficeC2RCOM component is not registered properly.

Resolution:


Stop the default vendor package servers (HP, DELL), restart Office C2R service, check in regedit for the keys HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\cloud\office\16.0\Common\officeupdate officemgmtcom = 1, HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\office\16.0\common\officeupdate officemgmtcom = 1 and run PS script to register Office C2RCOM component.

Once done the above changes, the impacted devices can able to detect and install O365 update.
