Details
Updated October 15, 2024: We have updated the rollout timeline below. Thank you for your patience.
Microsoft Teams tenants will soon be able to enable verification for anonymous meeting participants via CAPTCHA. This release of CAPTCHA Verification for Anonymous Meeting Participants will be rolling out across Microsoft Teams Desktop, Mobile and Web and will provide additional security against malicious bot and third-party app joins.
When this will happen:
General Availability (Worldwide): We will begin rolling out late October 2024 (previously early October) and expect to complete by mid-November 2024 (previously mid-October).
How this will affect your organization:
Tenants can enable anonymous meeting attendee verification via CAPTCHA in the Teams Admin Center. When enabled, any users that join the meeting as an anonymous user will be required to pass a CAPTCHA verification before landing in the meeting (including the meeting lobby, if enabled).
What you need to do to prepare:
This feature is off by default and Tenant Admins will need to enable CAPTCHA verification for their tenants through Meeting policies in the Teams Admin Center.
