On April 12th, Azure announced the General Availability of Azure AD B2B Collaboration. In a nutshell, it allows you to easily invite guests into your Azure Active Directory (AAD). As a Visual Studio Team Services customer, this enables you to invite guests into your AAD backed VSTS accounts in two steps:
Step 1: In the Azure portal, navigate to All users under your Active Directory. Click on the new button called “+ New guest user”.
From this screen, you can now invite any email address into your Azure AD. In this example, we are inviting a contractor, rob@contoso.com.
Step 2: The invited guest is immediately added to the Azure AD, which means you can invite them to your VSTS account without any delay:
Future Plans
Visual Studio Team Services are currently working on tighter integration with Azure AD. In the future, we will allow you to invite new AAD guests in one simple step from within your VSTS account, without needing to visit the Azure portal.
