Microsoft Teams for Windows is discontinuing support for the legacy ADAL Authentication SDK. Organizations that haven't transitioned to New Teams on Windows PCs may be impacted. New Teams removes support for ADAL, which may cause sign-in issues for impacted PCs. Organizations can identify if they rely on ADAL for Teams sign-in using Entra sign-in logs. If sign-in issues occur, organizations should try signing in to New Teams and contact their CSAM for further assistance.
