@dustinb3403 What do you mean disabling autodiscover for a user? Are you talking about a registry key?
No, within O365 you can either selectively disable authentication protocols because you're a glutton for punishment or you can do so with conditional access policies or Security Defaults.
Well you can disable Autodiscover as a whole organization through the modern authentication setting, however in order to have conditional access you have to have higher licensing than normal which is why I am confused at the disabling comment.
Just a P2 license to setup a conditional access license for the administrator account(s). The user accounts don't require this level of licensing.
Why is it a confusing question?
