Microsoft Teams for Windows is discontinuing support for the legacy ADAL Authentication SDK
Note: This message is relevant to organizations that haven’t yet fully transitioned to New Teams on Windows PCs. If every Teams user in your organization is already using New Teams, no further action is required.
New Teams removes support for ADAL (Active Directory Authentication Library), a legacy SDK used in rare cases by Teams Classic. This change is part of our broader effort to improve performance and security.
