Can not set O365 update channel

Question

I'm trying to change the update channel into my O365 to the Beta Channel, I have tried the manual way(as I used to do before)

• OfficeC2RClient.exe /changesetting Channel=BetaChannel

I have even assigned an Intune special policy to force the Beta update and excluded my machine from the company's O365 default policy, yet the channel is set to the Enterprise monthly one.
I have traced the registry keys as per MS Docs [Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\ClickToRun\Configuration] and located the main 2 keys:

1. CDNBaseUrl
2. UpdateChannel

Whenevr I setup the update channel manually to the beta channel value as per manage-office-365-proplus-updates

The update channel gets reset whenever any office application starts!!
Any help?

you could use these command to switch channel removing any policies

reg add HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration /v CDNBaseUrl /t REG_SZ /d "http://officecdn.microsoft.com/pr/5440fd1f-7ecb-4221-8110-145efaa6372f" /f  
reg delete HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration /v UnmanagedUpdateURL /f 2>nul  
reg delete HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration /v UpdateUrl /f 2>nul  
reg delete HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Configuration /v UpdateToVersion /f 2>nul  
reg delete HKLM\SOFTWARE\Microsoft\Office\ClickToRun\Updates /v UpdateToVersion /f 2>nul  
reg delete HKLM\SOFTWARE\Policies\Microsoft\Office\16.0\Common\OfficeUpdate /v UpdatePath /f 2>nul  
reg delete HKLM\SOFTWARE\Policies\Microsoft\Office\16.0\Common\OfficeUpdate /v UpdateBranch /f 2>nul  
reg delete HKLM\SOFTWARE\Policies\Microsoft\Office\16.0\Common\OfficeUpdate /v UpdateTargetVersion /f 2>nul

Answer 2

Hi,
Are you running the Office Automatic Update 2.0 task?
Any update channel in the environment needs to match the channel of the Office365 application.
After you change the channel, you'll need to update the app before the app shows the new update channel.
