Windows 10: Activation Error with Microsoft 365 A3 License

I have been trying to switch users over to use our Azure 365 A3 system but every time reimage a device and log in with a Microsoft 365 account it tells me windows is not activated. And that it cannot reach our organization activation server. Windows 10 and 11 activation keys come with Microsoft 365 A3 licensing correct? Thank you for any assistance you can provide.

Yes you are right. Office 365 does not include Windows License but we purchased Microsoft 365 A3 license which is included Office 365 + Windows + EMS. We can join Azure AD from my PC but when I tried to activate Windows it showed we can't activate Windows
on this device because you don't have a valid digital license or product key.
