On February 17, 2025, Microsoft began the deprecation of their legacy Outlook authentication, preventing applications relying on this method from reconnecting. Starting February 25, 2025, organizations that had already received the authentication update from Microsoft could no longer authenticate with the Clari Groove Outlook Add-In. The Clari Groove Engineering team promptly resolved the issue by updating the authentication method. This change was rolled out on March 03, 2025 at 16:00 UTC. No customer data was compromised during this incident.
