When will this change take place?
We've already started making this change. New Microsoft 365 tenants are created with Basic authentication already turned off as they have Security defaults enabled.
Beginning in early 2021, we started to disable Basic authentication for existing tenants with no reported usage. We always provide Message Center notifications to any customer prior to Basic authentication being completely disabled in their tenant.
In September 2021, we announced that effective October 1, 2022, we 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. See full announcement: Basic Authentication and Exchange Online – September 2021 Update
OAuth requires ReadSoft Collector version (6.5 >).
