Microsoft previously announced that Basic Authentication will be turned off in Exchange Online for Exchange ActiveSync (EAS), POP, IMAP, and Remote PowerShell starting with October 13, 2020. 'We still intend to move our customers away from Basic Authentication as we still very strongly believe improving security in Exchange Online benefits all of us, and so we’ll announce more accurate timelines for disabling Basic Authentication for tenants with usage at a later date.' Previously planned removal in October 2020

'We will also continue to complete the roll-out of OAuth support for POP, IMAP, SMTP AUTH and Remote PowerShell and continue to improve our reporting capabilities,' Microsoft said. However, starting October 2020, Microsoft will still automatically disable Basic Authentication for all newly created tenants and on those where it is not actively used. 'In response to the COVID-19 crisis and knowing that priorities have changed for many of our customers we have decided to postpone disabling Basic Authentication in Exchange Online for those tenants still actively using it until the second half of 2021,' Microsoft's Exchange team announced.

Microsoft says that Basic Authentication's removal from Exchange Online is being postponed until the second half of 2021 due to the current situation created by the COVID-19 pandemic.
