Removing the Outlook Add-in in the Microsoft 365 admin center

Overview

This article covers how to remove the Opensense Outlook Add-in from your Microsoft 365 environment in the Microsoft 365 admin center. Removing the add-in uninstalls it for all users in your deployment scope, which means your entire organization.

Only some users?

• To stop the add-in for some users, remove them from the scoped group instead. See Step 2 in Scoping Outlook Add-in users in the Microsoft 365 admin center.
• If a single user’s deployment is stuck and you only need to reset it, without affecting anyone else, see Step 7 in Troubleshooting the Outlook Add-in.

Before you remove the add-in

This process removes the add-in as a Microsoft 365 integrated app only. It doesn’t:

• Remove the Exchange mail flow rule that Opensense created for Stamping or Plain Text Block deployments
• Close or disconnect your Opensense account

If you’re fully offboarding, rather than removing the add-in for a while, contact help@opensense.com to coordinate removing the mail flow rule and any other cleanup.

Signatures stop for affected users

Removing the add-in stops Opensense signature behavior for all affected users. If your deployment uses Stamping or Plain Text Block, signatures are no longer applied to outbound email until the add-in is redeployed. If you’re unsure of the impact, talk to your Opensense account team before you remove it. The removal can take up to 72 hours to fully propagate to all users’ Outlook applications.

Only the admin who deployed the add-in, or a Global Administrator, can remove it. If another admin deployed it, the Remove button is unavailable.

Remove the add-in

1. Go to Integrated apps in the Microsoft 365 admin center, and sign in with your Microsoft 365 admin credentials when prompted. If the direct link doesn’t work, go to admin.microsoft.com, expand Settings in the left navigation, and select Integrated apps.
2. Find the Opensense app (Opensense Email Signatures) in the list of integrated apps, and select it to open its details.
3. Select the Configuration tab.
4. Select the add-in, and then select Remove.
5. Confirm the removal when prompted.

How to verify removal

Opensense no longer appears in the Integrated apps list. After 72 hours, ask an affected user to restart Outlook. Confirm that the Opensense add-in pane no longer appears, and, for Stamping or Plain Text Block deployments, that signatures are no longer applied.
