Reminder: Basic Authentication deprecation in Office Apps

Reminder: Basic Authentication deprecation in Office Apps

This post serves as an important reminder that Microsoft 365 Apps are set to disable server sign-in prompts that use Basic authentication in Office Apps starting from version 2301+. Basic authentication is a legacy authentication method, and using it sends a username and password with each request, which can be accessed by an attacker and used to access resources. Therefore, Microsoft is deprecating Basic Authentication from all tenants in favor of a more secure authentication method, preferably Modern Authentication, and enabling multi-factor authentication based on OAuth2.0 token-based auth. However, this retirement will not affect Exchange Online and Exchange on-premises.

It is recommended that organizations using Basic authentication to connect to Exchange or SharePoint Online switch to a more secure authentication protocol such as Modern Authentication. The change is expected to roll out starting January 23, 2023, and will impact users with Office Version 2301 or higher on their devices as they will no longer be able to access resources from servers using Basic authentication. It is therefore important for organizations to act now and make the necessary changes to avoid any potential disruptions.
