# Allow There emails in Microsoft 365

> Configure Microsoft Defender and Exchange Online when There sharing emails do not arrive or are marked as spam

This page is for Microsoft 365, Exchange Online, and Microsoft Defender for
Office 365 administrators. It explains how to allow There emails and links when
sharing messages do not arrive or are classified as junk mail.

## Symptoms

Microsoft filtering may be involved when:

* the user does not receive the sharing email;
* the email lands in junk mail;
* There shows that the email was sent;
* SMTP logs show that Microsoft accepted the delivery;
* no explicit bounce is returned to the sender.

In this case, allow the sending domain first, then the URLs used in sharing
links.

## Items to allow

Allow the following items in your tenant security policies:

| Item               | Where to add it       | Usage                                |
| ------------------ | --------------------- | ------------------------------------ |
| `there.do`         | Domains and addresses | Domain used for emails sent by There |
| `app.there.do/*`   | URL                   | Domain used for internal sharing     |
| `share.there.do/*` | URL                   | Domain used for public sharing links |

## Allow the sending domain

1. Open the
   [Tenant Allow/Block List](https://security.microsoft.com/tenantAllowBlockList)
   in Microsoft Defender.
2. If needed, the full path is **Email & collaboration** >
   **Policies & rules** > **Threat policies** > **Tenant Allow/Block List**.
3. Open the **Domains and addresses** tab.
4. Click **Add**.
5. Add `there.do`.
6. Save.

## Allow sharing URLs

After allowing the sending domain, add the domains used in sharing links.

1. In **Tenant Allow/Block List**, open the **URL** tab.
2. Click **Add**.
3. Add `app.there.do/*`.
4. Add `share.there.do/*`.
5. Save.
6. Send a new share from There to confirm delivery.

<Note>
  `app.there.do/*` covers internal sharing. `share.there.do/*` covers public
  sharing links.
