The Exchange team published an updated blog article in June regarding Basic Auth and Exchange Online: Basic Authentication and Exchange Online – June 2021 Update - Microsoft Tech Community.
In it The Exchange Team stated, "As we’ve said before, we’re only currently planning to turn off Basic Auth for those customers who are not using it. For customers that use still Basic for some or all the affected protocols*, we are not touching authentication settings for those protocols (for the time being)...We have been busy analyzing Basic Auth usage data for our customers and now have a solid understanding of who uses it and who does not. And we’re going to start turning it off for those who are not using it.
The process is: We’ll randomly select customers with no usage in any, or all affected protocols, send them a Message Center post informing them that in 30 days we’re going to turn off Basic Auth. 30 days later, we’ll turn it off and send another Message Center post to confirm it was done."
