I got a free Microsoft 365 Business Premium account to use WVD (Windows Virtual Desktop).
Microsoft 365 account: takayuki@bbbb.onmicrosoft.com
Azure AD tenant: aaaa.onmicrosoft.com (custom domain: aaaa.com)
Azure ADDS domain name: aaaa.com
To access WVD, your Microsoft 365 account
Did you need to get it at aaaa.onmicrosoft.com or aaaa.com?
Is there a way to link the bbbb.onmicrosoft.com account to the Azure AD account?
