Microsoft has issued what appears to be the final public warning about Basic Authentication in Exchange Online being deprecated next month. Customers have been advised to switch to Modern Auth.

Microsoft has once again informed customers that it is deprecating Basic Auth for many Exchange Online protocols starting from next month. However, tenants will be able to bypass it temporarily.

Google Workspace customers integrating Google Calendar and Exchange Online have been urged to make a configuration change before Microsoft disables an old authentication mechanism in October.

Microsoft has partnered with Apple on an upcoming iOS update that will migrate Exchange Online accounts using Basic authentication in the Mail app to the more secure Modern authentication (OAuth 2.0).

Microsoft has reminded organizations that it is deprecating Basic Auth for most protocols in Exchange Online in October 2022. The disabling process will be randomized so it's best to be prepared.
