If you cannot download via the link, you may try another option below.

Option 3: Deploy for your organization​

Use this option if an IT administrator will install Sonar for Outlook for users or groups.

  1. Sign in to the Microsoft 365 Add-ins page with an administrator account.

    If the direct link does not open, go to Settings > Integrated apps > Add-ins.

    Deploy Add-In on the Microsoft 365 Add-ins page

  2. Select Deploy Add-In, then select Choose from the Store.

    Choose from the Store

  3. Select Outlook from the left side panel, search for sonar, then click Add next to Sonar for Outlook.

    Add Sonar for Outlook

  4. Accept the terms and assign the add-in to users or groups authorized to use Sonar Legal. Start with a small pilot group, confirm that the add-in works, then expand the assignment to the remaining authorized users.

  5. Set the deployment method to Fixed, then select Deploy.

Users may need to restart Outlook. Microsoft advises that centrally deployed add-ins can take 24–72 hours to appear.

Important

Deploying the Outlook add-in does not automatically authorize all features. If you opt-in for the Sonar Legal agentic features, you will need to complete the M365 authorization by signing in to one of the pilot users.
