# Forward Lark Mail to Mermail

> Enable Lark Mail forwarding permissions and forward selected messages to a Mermail mailbox.

Lark Mail administrators must allow auto-forwarding before members can configure it. After permission is enabled, a member can forward all new messages or create auto filters for selected messages.

## Prerequisites

* A Mermail mailbox address.
* A Lark Mail member or public mailbox.
* A primary administrator or an administrator with Email permissions.
* Organization policy that permits sending mail to external recipients.

## Administrator: allow auto-forwarding

<Steps>
  <Step title="Open the Lark Admin Console">
    Go to the [Lark Admin Console](https://www.larksuite.com/admin).
  </Step>

  <Step title="Open forwarding permissions">
    Select **Product Settings** → **Mail** → **Email Management Tools** → **User Function Permissions** → **Auto Forward**.
  </Step>

  <Step title="Edit the permission">
    Click **Edit** and select **On** under **Permissions**.
  </Step>

  <Step title="Choose the scope">
    Select **Entire organization** or **Set range**. Use **Set range** when only specific member or public mailboxes should be allowed to forward externally.
  </Step>

  <Step title="Save">
    Save the permission change.
  </Step>
</Steps>

<Tip>
  Limit permission scope to the mailboxes that need Mermail. This reduces the number of accounts that can create external forwarding rules.
</Tip>

## Member: forward selected messages

<Steps>
  <Step title="Open auto filters">
    In Lark Mail, click the **Auto filters** icon and then **Create Auto Filter**.
  </Step>

  <Step title="Define the filter">
    Enter a name and add conditions for messages that are safe for Mermail AI to process.
  </Step>

  <Step title="Add the action">
    Under **Then do this**, select **Auto-forward to** and enter the Mermail mailbox address.
  </Step>

  <Step title="Create and verify">
    Click **Create**, then approve the verification message delivered to Mermail.
  </Step>
</Steps>

Lark allows up to five forwarding addresses through auto filters. Delete the destination from **Auto filters** when you want to stop selective forwarding.

## Member: forward all new messages

<Steps>
  <Step title="Open email settings">
    Click your profile photo and select **Settings** → **Email**.
  </Step>

  <Step title="Open Auto-forward">
    Under **Auto-forward**, click **Set Up Now**.
  </Step>

  <Step title="Add Mermail">
    Enter the Mermail mailbox address and click **Add**.
  </Step>

  <Step title="Verify the destination">
    Approve the verification message delivered to Mermail. Lark sends a notification after setup succeeds.
  </Step>
</Steps>

Lark allows up to two addresses for account-wide auto-forwarding.

<Info>
  For a public mailbox, switch to that mailbox before following the member steps. Administrator permission must include the public mailbox.
</Info>

## Test the setup

Send a new matching message. Lark does not forward existing messages, spam, messages addressed to a mailing list destination, or certain automatic replies.

## Stop forwarding

* For selected messages, delete the Mermail destination from **Auto filters**.
* For all messages, return to **Settings** → **Email** → **Auto-forward** → **Set Up Now**, then turn off **Enable auto-forward** for the address.

## Human takeover

If you reply to a forwarded thread directly in Lark Mail, Mermail treats the entire thread as human-managed and permanently stops AI processing for it.

## Troubleshooting

| Problem                             | What to check                                                        |
| ----------------------------------- | -------------------------------------------------------------------- |
| Members cannot configure forwarding | Confirm that an administrator enabled the permission for their scope |
| External addresses are rejected     | Check organization restrictions on sending to external recipients    |
| Old or spam messages are missing    | Lark forwards only eligible new messages and excludes spam           |
| The rule is inactive                | Complete destination verification in Mermail                         |
