What is causing the Update channel to change on our devices?

We are using Configuration Manager to deploy Semi Annual channel with ODT on our Win10 devices. Feature updates are also deployed through Configuration Manager.

The channel on our devices has changed to monthly on almost all of them. I'm unsure when this started, as this is an environment I inherited.

Things I have checked/performed,

If I install a new device and deploy Office 2202 Semi Annual to it, and check the registry, CDNBaseUrl and UpdateChannel are both http://officecdn.microsoft.com/pr/7ffbc6bf-bc32-4f92-8982-f9dd17fd3114 (semi annual)

When I then run the Office Automatic Updates 2.0 Scheduled task, UpdateChannel is changed to http://officecdn.microsoft.com/pr/55336b82-a18d-4dd6-b5f6-9e5095c314a6 (monthly)

If I run Office Automatic Updates 2.0 again, Office gets updated to 2208 on Monthly channel. The update is also fetched from Office CDN, despite "Management of Microsoft 365 Apps for enterprise" setting being enabled

How can I log and verify what exactly is causing the channel to change on our devices, and why the update is being fetched from Office CDN and not SCCM?

    I think I found the culprit, there are settings in the registry that are probably causing this,


    These settings seem to be retrieved from Microsoft 365 cloud service, as we have not configured them through GPO or ODT. I do not know how to remove them though. Apparently there is a Service Profile in play here, without any Service Profile being deployed.

    Hi, were you able to find a soltution?

    We just opened a ticket with microsoft and clicked on feedback to microsoft in the site config.office.com requesting to Opt-Out from the Monthly Maintenance Channel

    According to their documentation in this site:


    The registry key that you have shared is been created due to this change, we just don't know yet how to get rid of that policy, I'm hoping either the ticket or the request to opt-out will work
