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. We will provide a more precise date when we have a better understanding of the impact of the situation.
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. We will publish more details on these as we make progress.
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.
