B2B / Guest Access between Government (National Cloud) and Commercial Cloud timeline

Hi jebalert,

The rollout for Azure B2B for Azure Government/GCC High is a multi-phased approach.

Phase 1- We have recently rolled out Azure B2B for some GCC High tenants. This allows for two GCC High B2B enabled tenants to configure identity federation. We will eventually enable it for all GCC High tenants. When enabled it will allow for guest access/Teams collaboration between two GCC High tenants. 

Phase 2- We are developing the capability to enable GCC High tenants to enable B2B identity federation for the sharing of web docs (ODfB/SPO) to Commercial tenants and vice versa. 

Phase 3- We are developing the capability to enable GCC High tenants to enable B2B identity federation with Commercial tenants for the Teams client. This will enable external collaboration via Teams. 

The timelines for these phases are NDA so please connect privately with me or your account team. 

Here is the public documentation regarding Azure B2B for Azure Government:

• B2B Collaboration is available in Azure US Government tenants created after June, 2019. Over time, more tenants will get access to this functionality. See How can I tell if B2B collaboration is available in my Azure US Government tenant?

The following features have known limitations in Azure Government:

• Limitations with B2B Collaboration in supported Azure US Government tenants:

  • B2B collaboration is currently only supported between tenants that are both within Azure US Government cloud and that both support B2B collaboration. If you invite a user in a tenant that isn't part of the Azure US Government cloud or that doesn't yet support B2B collaboration, the invitation will fail or the user will be unable to redeem the invitation.
  • B2B collaboration via Power BI is not supported. When you invite a guest user from within Power BI, the B2B flow is not used and the guest user won't appear in the tenant's user list. If a guest user is invited through other means, they'll appear in the Power BI user list, but any sharing request to the user will fail and display a 403 Forbidden error.
  • Office 365 Groups are not supported for B2B users and can't be enabled.
  • Some SQL tools such as SSMS require you to set the appropriate cloud parameter. In the tool's Azure Service setup options, set the cloud parameter to Azure US Government.
