Microsoft Exchange Starts Discontinuing Basic Authentication Today

After years of constant warnings, Microsoft is now preparing to discontinue support for basic authentication via Exchange Online for good. Users who still only used this authentication format for their systems will no longer be able to do so in the coming days.

For users who are still using this authentication system, Microsoft recommends migrating to Modern Authentication (OAuth 2.0), which is considerably more secure.

Interestingly, this discontinuation will not be carried out immediately for all users. Instead, the company confirmed that the measure would start to be applied from today, but it will last for the next few weeks. However, eventually support will no longer be available to all Exchange Online customers.

The functionality can still be manually enabled for testing, but in January 2023 it will be permanently disabled for everyone. Therefore, regardless of this, it is recommended that users migrate to the most secure solution available. This measure also comes after years of constant warnings from Microsoft not to be used, which ended with the eventual discontinuation.
