outlook 2010 and 2013 continually asks for password in hybrid environment

Yes, I tried the registry key obviously with outlook 2013.
This weekend I reproduced an identical environment in the laboratory (which works with outlook 2010 and 2013)
The difference is that in the environment that does not work is that I have enabled https://docs.microsoft.com/en-us/exchange/configure-oauth-authentication-between-exchange-and-exchange-online-organizations-exchange-2013-help?redirectedfrom= MSDN it as HCW reported this warning:
warning HCW8064 The HCW has completed, but was not able to perform the OAuth portion of your Hybrid configuration. If you need features that rely on OAuth, you can try running the HCW again or manually configure OAuth using these manual steps
In the test infrastructure I have not implemented that functionality and both outlook 2010 and 2013 works.

By running the Get-OrganizationConfig | ft name, * OAuth * both on premises and on exchange online I get (the results are the same on both the test environment that works and the environment that doesn't work)
[PS] C:\Windows\system32>Get-OrganizationConfig | ft name, *OAuth*

Name OAuth2ClientProfileEnabled
---- --------------------------
First Organization False

mentre sull’exchange online è abilitata

PS C:\Users\challancin> Get-OrganizationConfig | ft name, *OAuth*

Name OAuth2ClientProfileEnabled
---- --------------------------
migexchange.onmicrosoft.com True

So I'm pretty sure the problem is https://docs.microsoft.com/en-us/exchange/configure-oauth-authentication-between-exchange-and-exchange-online-organizations-exchange-2013-help?redirectedfrom= MSDN
At this point I would like to understand how to disable it but I have not found any article.
I have already tried this article https://docs.microsoft.com/it-it/microsoft-365/enterprise/remove-or-disable-hybrid-modern-authentication-from-skype-for-business-and-excha? view = o365-worldwide without success.

Thanks
