# 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**.

:::tip[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](https://help.opensense.com/docs/clone-outlook-add-in-scope-users-for-opensense-in-m365-admin#step-2-add-users-to-the-scoped-group).
- 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](https://help.opensense.com/docs/outlook-add-in-troubleshooting-guide-2#step-7-regrant-admin-consent-and-reset-the-users-scope).
:::

## 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](mailto:help@opensense.com) to coordinate removing the mail flow rule and any other cleanup.

:::caution[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](mailto:help@opensense.com) 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](https://admin.microsoft.com/Adminportal/Home#/Settings/IntegratedApps) 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.

:::tip[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.
