Hi @McCambridge, John
Microsoft published this notice on February 14, 2024. Organizers and meeting participants in your organization who attend meetings with users outside of their organization - with or without a Microsoft Entra ID - will see the changes in labels that reflect the trust level of the participant with the organizer (External, Unverified, or no label).
- No label: All participants who are part of the organizer’s organization.
- External: All participants who are external to the organizer’s organization but have a trusted relationship with the organizer or their organization.
- Unverified: All other participants will be seen with this label. This will include Microsoft Entra ID users who belong to organizations that do not have an explicit external access setup with the organizer’s organization, Microsoft Account (personal) users, users who are not using any Microsoft ID while joining meetings, and others.
