The reason SMTP will still be available is that many multi-function devices such as printers and scanners can't be updated to use modern authentication. SMTP AUTH will still be available when Basic authentication is permanently disabled on October 1, 2022. The confusion only increases when I jump to this article that has two completely contradicting statements:Īny protocol exceptions or re-enabled protocols will be turned off early in January 2023, with no possibility of further use. As a result, there are no plans to disable Basic Authentication for SMTP AUTH clients at this time. Although SMTP AUTH now supports OAuth, most devices and clients have not been designed to use OAuth with SMTP AUTH. However, in the documentation this is stickied: We recommend using Modern Authentication when connecting with our service. During the first week of calendar year 2023, those protocols will be disabled for basic auth use permanently, and there will be no possibility of using basic auth after that.

In the article you linked this is also written: Selected protocol(s) will stay enabled for basic auth use until end of December 2022. Gorzelany Thanks for the reply! interesting read, it did however just serve to confuse me more.
