Azure Hybrid AD Domain Federation Requirements and set up?

Ben 20 Reputation points


First time doing something like this with Azure so I thought I'd take the plunge into the community.

I have two educational organisations which are federating each with their own hybrid Azure AD on their own domains. Each org has on-prem DCs and AD Connect server syncing with their own Azure AD and they each have their own SharePoints and O365 services.

They'd like to have a more seamless experience working and collaborating with eachother. My goal is to have a new top level domain under which the two current hybrid Azure AD domains can work and to set up trust relationships between them so I can work with them as if all under one domain.

Staff would like to be able to log in at any site with their own account from their own org.

The big question is, is this possible and if so what's the best route to take. If it isn't possible, what's the closest I could get to it?

Many thanks in advance!

    Did you explore the Cross Tenant Sharing feature? I think this should work in your favour as the Cross tenant feature is for this kind of requirements and scenarios -
