Windows Live Mail configuration

Hi. I have just purchased ParaInvite and am configuring the Windows Live Mail app. The setup described at https://www.simbunch[...]ll=&start=9 seems to have changed. Step 4 seems to have disappeared and has been replaced by something called Platforms. The redirect URL now seems to need a HTTPS not a standard HTTP. Is this related to these recent changes https://azure.micros[...]-oidc-changes/? I would be grateful for any guidance on how to configure this app. Many thanks.
