Basic Authentication and Exchange Online AMA

Hey Massimo, you can also use Auth Policies to do this - https://docs.microsoft.com/en-us/powershell/module/exchange/new-authenticationpolicy?view=exchange-ps You can set up a policy to block just POP and IMAP if you want to. You can also do this in Microsoft Admin Center - Org Settings, Modern Auth, the checkboxes there.
