SMTP AUTH Exception Smoothens Path to Removal of Basic Auth in Exchange Online – Office 365 for IT Pros

Last week’s announcement that Microsoft will disable basic authentication for Exchange Online connection protocols from October 2022 certainly got people’s attention. Hopefully the message is sinking in that it’s time to act to be prepared for a smooth switchover when Microsoft disconnects basic authentication in a year’s time. Given the number of Office 365 tenants out there, it’s discouraging that Microsoft’s article received only 29K views as of 9:30 AM UTC today. Some people might be going to receive a terrific surprise when the hammer descends.
