Basic Authentication retirement in Microsoft 365 Apps

If you are using Basic Authentication to access resources in Microsoft 365 Apps, be aware of the upcoming change. Basic Authentication is a legacy authentication method that sends a username and password with each request, which poses a security threat to organizations. As a result, Microsoft 365 Apps will disable server sign-in prompts that use Basic Authentication in Office Apps from version 2209+. Instead, it's recommended to switch to a more secure authentication method such as Modern Authentication and enable multi-factor authentication based on OAuth2.0 token-based authentication. Organizations with on-premises servers may need to take action to prepare for this change, as users with the Office Version 2209 or higher on their devices will not be able to access resources from servers that use Basic Authentication. The change will begin rolling out in early January 2023 and is expected to be completed by early February.
