Hi AMA! Conditional Access Policies in Azure AD allows to choose "Other Clients" when blocking Legacy Auth in advance to see an expected impact, but you can't just disable IMAP and POP and leave SMTP open. Is there a way to create a CAP in advance so that we can block Basic for IMAP and POP only without impacting SMTP?

Adding some notes here. I have a few companies (5000-10000 mailboxes each) without CA because they don't have AADP1. Any additional test to evaluate the impact in advance?

    In that case I'd suggest getting into the Azure AD Sign In Logs and looking for usage. Or just setting an Auth Policy - and waiting to see what happens... 😉
