What the notice says
Microsoft’s text, safely structuredIntroduction
One-time Email Passcodes provide a way for tenant administrators and event organizers to verify anonymous, external presenters invited to Microsoft Teams events. When enabled, anonymous external presenters are prompted to enter a one-time email passcode before joining an event and receive a Verified label next to their name after joining.
External presenters with personal or work Microsoft accounts are asked to sign in to their account for verification instead of receiving a one-time email passcode.
This message is associated with Microsoft 365 Roadmap ID 557975.
When this will happen
- Targeted Release: We will begin rolling out late April 2026 and expect to complete by early May 2026.
- General Availability (Worldwide): We will begin rolling out mid-May 2026 and expect to complete by late June 2026.
How this affects your organization
Who is affected
- Tenant administrators managing Microsoft Teams policies
- Event organizers scheduling Teams events with external presenters
- External presenters joining Teams events anonymously
What will happen
- Tenant administrators can require verification for anonymous external presenters by configuring a new Teams Admin Center policy or by using PowerShell.
- Based on the tenant-level policy, event organizers will have additional options that apply to all external presenters for an event:
- Verify external presenters, allowing only invited accounts to join.
- Verify external presenters, allowing uninvited users to wait in the lobby.
- No verification (available only if the tenant policy also allows no verification).
- This distinction allows organizers to restrict an event to invited external presenters or allow more flexibility by permitting uninvited users with the event link to join through the lobby.
- By default, the policy is set to None, allowing external presenters to join anonymously.
- When the policy is set to eOTP, all external presenters must verify their identity either by signing in with a Microsoft account or by entering a one-time email passcode.
What you can do to prepare
- Review how external presenters are used in your Teams events.
- Decide whether anonymous external presenters should be required to verify their identity.
- Configure the external presenter verification policy in the Teams Admin Center or by using PowerShell.
- Inform event organizers about the new verification options available to them.
