Setting up multiple signatures in the Outlook Add-in
Overview
Section titled “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
Section titled “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.
Configuring default and secondary templates
Section titled “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.
- Assign the default template (for example, to an
allusersgroup) at the top, so it acts as the fallback priority for everyone. - List secondary templates below the default. Assign them by department when specific users need different signatures.
- To change the order, select Change Priority, and rearrange the routes.

Template behavior by device
Section titled “Template behavior by device”Reset vs. save user choice
Section titled “Reset vs. save user choice”The Allow Default Override (Multiple Signature) setting in Domain Settings controls whether a user’s selection carries over between compose sessions.
- Off
- 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.
- On
- Users keep their last selected signature across compose sessions.
Enabling and testing
Section titled “Enabling and testing”- Turn on Multiple Signatures in Domain Settings, so users can select from a drop-down menu in the add-in pane.
- Open the add-in as a test user, and confirm that the drop-down shows all the expected signature options.
- Switch between signatures, and send a test email from each one to confirm that routing applies the correct template.
