# Setting up multiple signatures in the Outlook Add-in

## Overview

The Multi-Signature Selector lets users switch between multiple assigned signatures in the Outlook Add-in. This is useful for organizations where employees need different signatures based on department, role, or use case. For example, a salesperson who needs a marketing-focused signature and a support-focused one.

This article explains how to turn on multi-signature selection, configure signature priority, understand behavior across devices, and manage whether a user's selection persists between compose sessions.

## Before you start

You need:

- Domain Admin access in the Opensense portal
- Signature templates already created for each option you want available. If you haven't configured Domain Settings yet, see [Configuring the Outlook Add-in in Domain Settings](https://help.opensense.com/docs/clone-outlook-add-in-domain-settings-with-scenarios-and-best-practices).

## Configuring default and secondary templates

Signature priority comes from the order of your routes on the **Routing** page (**Signatures** > **Routing**). Opensense follows this order when it matches signatures with user groups. The screenshot below shows an earlier version of the portal, where Routing was under **Manage**.

1. Assign the default template (for example, to an `allusers` group) at the top, so it acts as the fallback priority for everyone.
2. List secondary templates below the default. Assign them by department when specific users need different signatures.
3. To change the order, select **Change Priority**, and rearrange the routes.

![Routing page with three routes in priority order: route 1 assigns a signature to the allusers group, and routes 2 and 3 assign signatures to a cs_test group, with a Change Priority button above them](https://help.opensense.com/media/image1-2-749b6c510d64.png)

:::tip[No default signature needed?]
If users don't need a default signature, but do need multiple options, prioritize routes or departments based on the signatures each group needs.

## Template behavior by device

<div class="kb-deployment-compare kb-deployment-compare--plain">
  <div class="kb-deployment-compare__viewport" role="region" aria-label="Signature selection by device and deployment" tabindex="0">
    <table>
      <colgroup><col class="kb-deployment-compare__feature-col"></colgroup>
      <thead>
        <tr>
          <th scope="col">Where</th>
          <th scope="col"><span class="kb-deployment-compare__method">Deployment</span></th>
          <th scope="col"><span class="kb-deployment-compare__method">Which signature is used</span></th>
        </tr>
      </thead>
      <tbody>
        <tr>
          <th scope="row">Mobile</th>
          <td>Stamping</td>
          <td>The top-priority (default) template, applied automatically through stamping</td>
        </tr>
        <tr>
          <th scope="row">Desktop, OWA, and Outlook Mobile</th>
          <td>Non-stamping</td>
          <td>The signature the user selects in the Outlook Add-in pane</td>
        </tr>
      </tbody>
    </table>
  </div>
</div>

## Reset vs. save user choice

The [Allow Default Override (Multiple Signature)](https://help.opensense.com/docs/clone-outlook-add-in-domain-settings-with-scenarios-and-best-practices#allow-default-override-multiple-signature) setting in Domain Settings controls whether a user's selection carries over between compose sessions.

<dl class="kb-insights-summary">
  <div><dt>Off</dt><dd>Users always reset to the default (priority) signature on each new compose. Use this if you need to go back to strict priority-based signature assignment.</dd></div>
  <div><dt>On</dt><dd>Users keep their last selected signature across compose sessions.</dd></div>
</dl>

## Enabling and testing

1. Turn on [Multiple Signatures](https://help.opensense.com/docs/clone-outlook-add-in-domain-settings-with-scenarios-and-best-practices#multiple-signatures) in Domain Settings, so users can select from a drop-down menu in the add-in pane.
2. Open the add-in as a test user, and confirm that the drop-down shows all the expected signature options.
3. Switch between signatures, and send a test email from each one to confirm that routing applies the correct template.

:::tip[How to verify]
The test user sees the expected signatures in the drop-down, and each test email shows the signature selected at send time.
