Teams introduces automatic blocking of external bots in meetings
Microsoft is rolling out a new Teams meeting protection policy that automatically blocks identified external bots from joining meetings, building on a June feature that tagged bots and required organizer approval. After activation in the Teams admin center under Manage bots, admins can assign the policy to specific users or groups; the setting is off by default and will be rolled out to general availability by late September following a targeted release through August. The change helps prevent third-party and potentially malicious bots from joining meetings without attendees’ knowledge and complements other security measures, with Microsoft planning additional admin controls like bot allow lists and audit logs.
