Office365 帐号可以用Basic Authenticat

As of October 1, 2022, Microsoft has deprecated Basic Authentication for Office 365 (now known as Microsoft 365) in favor of Modern Authentication (OAuth 2.0). Basic Authentication is less secure because it requires sending the username and password with every request, whereas Modern Authentication uses token-based authentication, which is more secure.

Implications of Deprecation:

• Increased Security: Modern Authentication provides enhanced security by not relying on usernames and passwords being sent over the network. Instead, it uses tokens and supports multi-factor authentication (MFA).
• User Experience: Applications using Modern Authentication can provide a better user experience with single sign-on (SSO) and conditional access policies.

Applications and Services Affected:

• Outlook: All versions of Outlook that are capable of using Modern Authentication are required to do so. This includes Outlook 2013 and later, with proper updates.
• Third-Party Apps: Any third-party mail applications that previously relied on Basic Authentication must be updated to support Modern Authentication. This includes apps on mobile devices and other email clients.

Recommendations:

• Upgrade Clients: Ensure all email clients and apps are updated to versions that support Modern Authentication.
• Use App Passwords: For apps that do not support Modern Authentication, app passwords can be used as a temporary solution. However, it's recommended to transition to apps that fully support Modern Authentication.

Additional Information:

• Microsoft provides extensive documentation and resources to assist with the transition from Basic to Modern Authentication. You can find more details and updates on their official Microsoft 365 Blog and Microsoft Docs.

In conclusion, it is no longer possible to use Basic Authentication for Office 365 mail apps, and all users and administrators should ensure they are using Modern Authentication for improved security and compliance with Microsoft’s policies.
