I am testing switching between ADFS and PHS in my test environment. The authentication was original setup as ADFS and I was able to switch to PHS by using ADconnect alone (without need to use set-msoldomainauthentication cmdlet). I then rollback to ADFS by using convert-msoldomaintofederated and that is also working. Get-msoldomain showed the domain is federated and I was redirected to the ADFS page to sign-in. However, when I try to switch from ADFS to PHS the 2nd time, the user sign-in options is already set to PHS in ADconnect. I can't change from ADFS to PHS which the options in the ADconnect wizard. Can someone explain what did I miss during these changes?
Thanks
