Hi,
At this moment B2B isn't supported for Azure Virtual Desktop:
The user must be sourced from the same Active Directory that's connected to Azure AD. Azure Virtual Desktop does not support B2B or MSA accounts. The UPN you use to subscribe to Azure Virtual Desktop must exist in the Active Directory domain the VM is joined to.
It would be nice to create a B2B feature, so our end users can use AVD resources from our third party suppliers (DaaS/SaaS suppliers). This way will increase the user experience.
I think B2B is the future, it's already present in other Azure resources like Teams, Office 365, OneDrive, Sharepoint etc.
Discuss this already with Pedro Magrico.
