Authentication and sharing between trusted tenants

[Darren Neimke]

I have two organisations who want to add users from one directory into the other without External Sharing - e.g. the old two-way trust in AD.

Is it possible with AAD to achieve the same result without having to invite each individual user.

The easiest way to do that is with Azure AD B2B, see https://azure.microsoft.com/en-us/documentation/articles/active-directory-b2b-collaboration-overview...
