HighAvilabilty (Primary site and DR Site) ADFS and Proxy server with office 365

In my post above I was writing “adds” which of course means ADFS :) (auto correct!! )

Of course! Just add additional adds servers in the adds farm! And add an additional wap server!

Please read the official doc here:

https://docs.microsoft.com/en-us/office365/enterprise/deploy-high-availability-federated-authentication-for-office-365-in-azure

Also there are lots of resources online you can search for regarding setting this up!
