Please add the UPN (your office 365 custom domain) in your AD and attach this to your users in AD as their UPN! This change should now sync!
If they are hybrid joined they should be able to login with their UPN now

Also: make sure that the GPO for "Do not connect to any Windows Update Internet locations" is TURNED OFF!

Just to make sure: Do your licenses include Windows 10??

how about if you are upgrading items below?

- Windows 10 home to Windows 10 pro?

- Windows 10 pro to Windows 10 Enterprise?

Windows 10 home to Windows 10 pro?

You need either Windows 10 Pro, or Windows 7/8.1 Pro to upgrade.

Windows 10 pro to Windows 10 Enterprise?

This is supported. For both M365 Business and M365 Enterprise paths, simply add the licensing to each user, then sign that user into Azure Active Directory. When each user with a valid M365 Windows entitlement signs in, their Operating System will slipstream upgrade to either Windows 10 Business or Windows 10 Enterprise from Windows 10 Pro. If that user removes their Azure Active Directory sign-in, their Operating System will revert back to Windows 10 Pro.

I'm trying to setup Windows 10 subscription activation using M365. When you say "sign that user into Azure Active Directory". Do you mean add the AAD user as an account in settings on the Windows 10 computer? I've tried that and it hasn't worked?
This user has an M365 A3 licence in Office 365 and is running on a Windows 10 Pro machine.

Thanks,
Nigel

  You have to (hybrid )join the machine to azure either with an Ad service connection point or manually! The documentation explains this

    The on-prem AD has Azure AD connect setup and the machines are hybrid joined using that. The AD users and computers appear in the Azure AD and I've assigned the AD users an A3 licence in Office 365. The AD has an internal domain name so the users appear in Azure AD as an onmicrosoft.com domain. I'm just missing the probably obvious last step of how these users then activate the Windows 10 subscription so that the Windows 10 pro computer becomes enterprise.
    I can't logon to the Windows 10 computer using the Azure AD username (user@<mydomain>.onmicrosoft.com) so I'm not sure what "sign in to the Azure AD" means in the earlier part of the thread to enable the activation. Or exactly what documentation is this from as I've followed all I could find?
    
    Thanks,
