Issue
Applications have used Basic authentication to connect to servers, services, and API endpoints.
Basic authentication, however, is an outdated industry standard.
In September 2021, Microsoft announced that effective October 1, 2022, they will begin disabling Basic authentication for Outlook, EWS, RPS, POP, IMAP, and EAS protocols in Exchange Online. SMTP Auth will also be disabled if it is not being used.
