# Invitee domain lists

Control which participant email domains Cogram is allowed or blocked from joining meetings with.

Cogram can be configured to only join (or never join) meetings that include participants from specific email domains. This is useful for enforcing privacy boundaries, such as preventing Cogram from recording meetings with external parties.

These settings are under [Account Settings > Meetings](https://app.cogram.com/dashboard/settings/account-settings/meetings).

## Allow List

When an allow list is set, Cogram will only join meetings where all participants are from one of the listed domains. Meetings that include participants outside the listed domains will not be attended.

Leave the allow list empty to place no domain restrictions of your own. If your organization has set an allow list, it still applies.

## Block List

When a block list is set, Cogram will not join any meeting that includes a participant from one of the listed domains, even if you have scheduled it to attend. Domains set by your organization apply on top of your own list.

## Live meeting links

Cogram cannot see who is in a meeting before it joins, so it cannot check a pasted live meeting link against your lists. While either list has any domain in it, one of two things happens on the Calendar page, and your Org Admin chooses which:

| Mode                       | What you see                                                                                                                                                                                                     |
| -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Blocked** (default)      | You cannot paste a live meeting link. The form is disabled and explains why. When your organization allows calendar invites, it also points you to your calendar. You can remove any domains you added yourself. |
| **Allowed with a warning** | You can paste a live meeting link. When you select **Attend now**, Cogram names the restricted domains and warns that it cannot check them. Select **Attend anyway** to continue, or **Cancel** to stop.         |

In both modes, Cogram still checks the invitees of meetings you schedule from your calendar against your lists.

### Choosing the mode (Admins)

Org Admins and Owners choose the mode under [Organization Settings > Meetings](https://app.cogram.com/dashboard/settings/admin/meetings) > Attendance controls, in the **"Invitee domain lists and live meeting links"** block under the two list fields. The mode applies to the whole organization; there is no group or personal override, and it has no effect while no list is configured.

## Setting defaults for your organization (Admins)

Org Admins and Owners can set and lock domain lists for all members under [Organization Settings > Meetings](https://app.cogram.com/dashboard/settings/admin/meetings). This is useful for enforcing a consistent privacy policy across the organization.

| State        | What the end user sees                                                                                                             | What Cogram enforces                                               |
| ------------ | ---------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------ |
| **Unlocked** | The personal list starts empty and never shows the org domains. The user can add their own domains and remove the ones they added. | The org list and the user's own list both apply.                   |
| **Locked**   | The field is grayed out with a lock icon. The user cannot modify the list.                                                         | Only the org list applies. Group and personal entries are ignored. |

Lock the list and leave it empty to switch the domain lists off for the whole organization, including any entries members added themselves.

> **Note**: If your organization has locked these settings, you will not be able to edit the domain lists. Contact your Org Admin if you need them changed.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cogram.com/meetings/invitee-domain-lists.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
