# Pinning Lanten in Outlook

> Pin the panel once and Lanten opens beside every email you read.

By default, Outlook closes an add-in when you move to the next email. Pinning fixes that: once pinned, Lanten sits beside every email you open — which is the whole point of an ambient co-pilot.

## Pin it

<Tabs>
  <Tab title="New Outlook (Windows)">
    1. Open any email and launch Lanten (via the Lanten icon on the message, or **Apps**).
    2. At the top of the panel, click the **pin** icon.
    3. Move to another email — Lanten stays open and updates to the new sender.
  </Tab>

  <Tab title="Classic Outlook (Windows)">
    1. Open an email and launch Lanten from the ribbon.
    2. Click the **pin** icon in the top-right of the panel.
    3. The panel now stays open as you move through your inbox.
  </Tab>

  <Tab title="Outlook on the web">
    1. Open an email, click **Apps**, and choose Lanten.
    2. Click the **pin** icon at the top of the panel.
  </Tab>

  <Tab title="Outlook for Mac">
    1. Open an email and launch Lanten.
    2. Click the **pin** icon at the top of the panel.
  </Tab>
</Tabs>

<Tip>
  Pinning keeps the panel open, but you can also make Lanten's icon appear directly on every message so it's one click away even when unpinned — see [Customising reading-pane actions](/outlook/reading-pane-actions).
</Tip>

No pin icon, or no Lanten at all? Head to [Lanten isn't showing in Outlook](/troubleshooting/add-in-not-showing).
