 Use the IIS Authentication section of the Azure Multi-Factor Authentication (MFA) Server to enable and configure IIS authentication for integration with Microsoft IIS web applications. The Azure MFA Server installs a plug-in that can filter requests being made to the IIS web server to add Azure Multi-Factor Authentication. The IIS plug-in provides support for Form-Based Authentication and Integrated Windows HTTP Authentication. Trusted IPs can also be configured to exempt internal IP addresses from two-factor authentication.
 
 > [!IMPORTANT]
-> As of July 1, 2019, Microsoft no longer offers MFA Server for new deployments. New customers that want to require multi-factor authentication (MFA) during sign-in events should use cloud-based Azure AD Multi-Factor Authentication.
->
-> To get started with cloud-based MFA, see [Tutorial: Secure user sign-in events with Azure AD Multi-Factor Authentication](tutorial-enable-azure-mfa.md).
->
-> Existing customers that activated MFA Server before July 1, 2019 can download the latest version, future updates, and generate activation credentials as usual.
+> In September 2022, Microsoft announced deprecation of Azure Multi-Factor Authentication Server. Beginning September 30, 2024, Azure Multi-Factor Authentication Server deployments will no longer service multifactor authentication (MFA) requests, which could cause authentications to fail for your organization. To ensure uninterrupted authentication services and to remain in a supported state, organizations should [migrate their users’ authentication data](how-to-migrate-mfa-server-to-azure-mfa-user-authentication.md) to the cloud-based Azure MFA service by using the latest Migration Utility included in the most recent [Azure MFA Server update](https://www.microsoft.com/download/details.aspx?id=55849). For more information, see [Azure MFA Server Migration](how-to-migrate-mfa-server-to-azure-mfa.md).

 > When you use cloud-based Azure Multi-Factor Authentication, there is no alternative to the IIS plugin provided by Azure Multi-Factor Authentication (MFA) Server. Instead, use Web Application Proxy (WAP) with Active Directory Federation Services (AD FS) or Azure Active Directory's Application Proxy.
