Microsoft Teams Enhances Bot Protection to Prevent Unauthorized Access

Microsoft has introduced a new policy for Teams that prevents unauthorized third-party bots from joining meetings without approval. This feature, announced on June 30, 2026, allows meeting organizers to manage bot access more effectively, addressing security risks associated with automated tools. Bots that are detected are placed in a lobby for manual approval, enhancing control over meeting participants. Microsoft plans to implement additional features, including allow lists and audit logs, to further strengthen security. The rollout comes amid rising concerns over bots being used for malicious purposes, including impersonation and social engineering attacks. This update is part of a broader initiative to improve security in Teams, which has seen increased abuse by cybercriminals. The new controls are expected to be available across various platforms including Windows, macOS, Android, and iOS.

Key Points: • Microsoft Teams now requires approval for third-party bots to join meetings. • Detected bots are placed in a lobby for manual verification by meeting organizers. • The new policy aims to mitigate risks associated with automated tools in sensitive discussions.
