So if a guest clicks on the Teams invitation link in the email they receive, they get the option to launch and login to the desktop app. This appears to be the preferred MS option. Because we've not allowed guests to use the desktop client in one of our Conditional Access policies, this will fail. We need to remove the desktop app as an option entirely and only offer the login to the web app, or launch straight into the web app. We want there to be no way the guest can get confused.
I just don't see this as a customisable thing at the moment. is this correct?
