Overview
This article covers how to remove the Opensense Outlook Add-in from your Microsoft 365 environment via the Microsoft 365 Admin Center. Removing the add-in uninstalls it from all users in your deployment scope. This removes the add-in for your entire organization, if a single user's deployment is stuck and you just need to reset it without affecting anyone else, see Step 7 in the Outlook Add-in Troubleshooting Guide instead.
This process removes the add-in as a Microsoft 365 Integrated App only. It does not remove the Exchange mail flow rule Opensense created for stamping or plaintext block deployments, and it does not close or disconnect your Opensense account. If you're fully offboarding rather than temporarily removing the add-in, contact help@opensense.com to coordinate removing the mail flow rule and any other cleanup.
Removing the add-in stops Opensense signature behavior for all affected users. If your deployment uses stamping or the plaintext block, signatures will no longer be applied to outbound email until the add-in is redeployed. Coordinate with your Opensense account team before removing if you are unsure of the impact. It can take up to 72 hours for the removal to fully propagate to all users' Outlook applications.
Steps
Step 1: Access Integrated Apps
Go to Integrated Apps in the Microsoft 365 Admin Center.
If the direct link does not work, navigate to admin.microsoft.com, expand Settings in the left navigation, and select Integrated Apps.
Sign in with your Microsoft 365 Admin credentials when prompted.
Step 2: Remove the add-in
Locate Opensense in the list of integrated apps.
Click the Opensense app to open its details.
Click Remove.
Confirm the removal when prompted.
How to verify it's removed: Opensense no longer appears in the Integrated Apps list. After 72 hours, ask an affected user to restart Outlook and confirm the Opensense add-in pane no longer appears and, for stamping or plaintext block deployments, that signatures are no longer being applied.
