Bypass Lobby for invited users but not working for external users added in the organization.

We need to set the 'who can bypass lobby' option to 'invited users'. However if the invited user is an external user in this tenant than the identity becomes different than the invited user and the user cannot bypass lobby.

Any work around?

    The People who were invited setting does support guest and external users, but Teams must be able to identify them as the account that received the invitation. Microsoft documents that invited work/school accounts and guests can bypass the lobby, while users who cannot be identified as the invited account will not.

    First make sure the meeting invitation is sent to the exact account/guest identity the user will use to sign into Teams, and have the user join while signed into that account.

    If these users already exist as B2B guests in your tenant, another option is:

    Teams meeting > Meeting options > Who can bypass the lobby > People in my org and guests

    That removes the requirement for Teams to match the guest specifically against the meeting invitation. However, the tradeoff is that all authenticated guests in the tenant can bypass the lobby, not only the guests specifically invited to that meeting.

    If the requirement is strictly "only specifically invited users can bypass," there isn't a separate setting that overrides an identity mismatch. The invited identity and the identity used to join need to match.

    Hi Haiqa,

    The AI-generated answer already covers the expected behavior of the People who were invited lobby setting and the available configuration options. As an additional step, I would recommend verifying that the email address used in the meeting invitation matches the participant’s actual Microsoft Teams sign-in account, rather than an alias or alternate email address.

    It may also be helpful to ask the participant to sign out of any other Microsoft accounts before joining the meeting. Alternatively, they can open the meeting link in an InPrivate or Incognito browser window and sign in using the exact account that received the invitation.

    If the behavior continues, a Teams administrator can run the Lobby Access diagnostic for the affected participant and meeting. This diagnostic helps validate the expected lobby experience, reviews the applicable configuration, and can identify settings that may be contributing to the issue.

    If Teams is still unable to match the participant's authenticated identity with the identity associated with the invitation, the remaining option while keeping People who were invited enabled is for an organizer, co-organizer, or presenter to admit the participant manually from the lobby.

    I hope this information helps clarify the behavior. If you have any further questions, please feel free to let me know.

    Best regards.

    People who were invited only lets participants bypass the lobby if they have the invitation itself and are signed in with a recognized work or school account or guest identity. It does not include people who only have the join link, and it does not include participants who aren’t signed in.

    For external users, the key limitation is identity matching:

    • The setting includes guests and work or school accounts to whom the invite was forwarded.
    • If the external person joins with a different identity than the one tied to the invitation or guest account, Teams won’t treat them as an invited participant for lobby bypass.
    • In that case, they wait in the lobby.

    Supported workarounds:

    1. Ensure the external participant joins with the exact invited identity.
      • If the user was added as a guest in the tenant, the user must join with that guest-associated identity.
      • If the user joins with another account, Teams can treat them as a different participant.
    2. Disable invite forwarding if only directly invited identities should bypass the lobby.
      • The People who were invited setting includes forwarded invites.
      • Turning off forwarding helps restrict bypass to the intended identities.
    3. If identity mismatch is expected, use a different lobby setting.
      • People in my org and guests allows people in the organization and people with guest access to bypass the lobby.
      • People in my org, trusted orgs, and guests also allows trusted external organizations and guests to bypass.
      • Everyone allows anyone with the meeting link to join directly, subject to admin policy behavior for some anonymous, untrusted, or dial-in participants.
    4. Verify external access prerequisites at the tenant level.
      • Guest access must be enabled for guests.
      • External access must be enabled for trusted organizations.
      • Anonymous meeting join must be enabled if anonymous participants are expected.
      • If any of these are off, that participant type can’t join as expected regardless of lobby settings.

    If the requirement is specifically “only invited users bypass the lobby,” there is no separate workaround in the documented behavior for external users joining under a different identity. The practical options are to make them join with the exact invited identity or choose a broader bypass setting that matches how those users authenticate.

    To change the meeting-level setting in Teams:

    1. Open Calendar in Teams.
    2. Select the meeting.
    3. Select View event.
    4. Select Options.
    5. Under Meeting access, change Who can bypass the lobby?.
    6. Select Apply.
