Outlook Add-in (Setup)

Enable the Langdock Outlook add-in for your workspace so users can access Langdock directly inside Microsoft Outlook.

The Outlook add-in brings Langdock directly into Microsoft Outlook, allowing users to summarize threads, triage inboxes, draft replies, and schedule meetings without leaving Outlook. Users need a mailbox in Exchange Online and a supported Outlook client, see the requirements in the user guide. This section covers how to enable the add-in for your workspace.

Enabling the add-in

1. Open integration settings

   Navigate to your workspace integration settings in Langdock.

2. Enable the add-in

   Find the Outlook add-in and toggle it on.

   

The add-in uses the Outlook Email and Outlook Calendar integrations to read messages, search mailboxes, and work with calendars. Make sure both are enabled in your workspace, since users are asked to connect them when they first open the add-in.

Users can now sign in to the add-in from within Outlook. Share the Outlook add-in overview with your users so they know how to get started.

Enabling the add-in for dedicated deployments

Before you start, make sure you have Microsoft admin access to the Microsoft 365 Admin Portal and Langdock admin access to your Workspace.

Setting up the Outlook add-in involves three parts:

1. A Microsoft admin deploys the custom app in the Microsoft 365 Admin Portal
2. A Langdock admin enables the Outlook add-in in Langdock as described above
3. Each user opens the Add-in in Outlook and signs in

After setup, users in the assigned Microsoft 365 target group can open the Langdock Add-in directly from Outlook.

Upload the custom app in Microsoft 365

This step must be completed by a Microsoft admin.

1. Open Integrated apps

   Navigate to Settings > Integrated apps in the Microsoft 365 Admin Portal sidebar.

   
2. Upload the custom app

   On the Integrated apps page, click Upload custom apps.

   
3. Configure the app deployment

   In the New App Deployment window, select:

   • App type: Office Add-in
   • Upload option: Provide link to manifest file
   • Manifest link: https://<your-deployment-url>/api/addin/dedicated/outlook/manifest.xml

   Click Validate. After the manifest file validates successfully, click Next.

   
4. Assign the target group

   Choose who should get access to the Outlook add-in, then click Next.

   • Select Entire organization if every user in your Microsoft 365 tenant should get access.
   • Select Specific users/groups if you want to roll out the add-in to a smaller group first.
   • Select Just me only if you want to test the add-in before a wider rollout.

   
5. Finish deployment

   Review the configuration and click Finish Deployment.

   
6. Confirm the Add-in appears

   Confirm that the Add-in appears on the overview page.

   

Once deployment is complete, share the Outlook add-in installation guide with your users so they can open the Add-in and sign in.

Update the add-in in Microsoft 365

When Langdock releases a new version of the Outlook add-in, for example with a new name or icon, a Microsoft admin applies it once for your organization. Microsoft doesn’t update custom add-ins automatically. Update the existing Add-in instead of uploading it again, so users don’t see it twice.

1. Open the Add-in

   Navigate to Settings > Integrated apps in the Microsoft 365 Admin Portal and select the Outlook add-in you deployed.

2. Update the manifest

   Click Update add-in. Provide the same manifest link you used during setup, https://<your-deployment-url>/api/addin/dedicated/outlook/manifest.xml, and click Validate.

3. Finish the update

   Keep the existing target group, then click Accept and update.

Microsoft can take up to 72 hours to roll out the update. Users see the new version the next time they start Outlook.

Removing the add-in

How you remove the Outlook add-in depends on how it was installed. If a Microsoft admin deployed it in Integrated apps, which is always the case on dedicated deployments, the admin removes it there for everyone. If someone installed it from the Microsoft Marketplace with Get it now, it belongs to their own mailbox and stays after the admin deployment is removed, so they remove it in Outlook. Turning the add-in off in the Langdock integration settings doesn’t uninstall it, it only stops users from using it.

Remove the add-in in Microsoft 365

This step must be completed by a Microsoft admin.

1. Open the Add-in

   Navigate to Settings > Integrated apps in the Microsoft 365 Admin Portal and select the Outlook add-in you deployed.

2. Remove the Add-in

   On the Overview tab, choose to remove the app. Select Yes, I’m sure I want to remove the app and associated data and click Remove.

Microsoft can take up to 24 hours to remove the add-in for all users. It disappears the next time they start Outlook. If it’s still listed after that, clear the Office add-in cache on that device and restart Outlook.

Remove the add-in from your own Outlook

If you installed the add-in yourself from the Microsoft Marketplace, for example while testing, remove it in Outlook. This copy stays even after the admin deployment is removed.

1. Open your apps

   In Outlook, select More apps > Add apps, or All apps > Add apps in classic Outlook, and click Manage your apps.

2. Remove Langdock

   Find Langdock in the list, select More options > Remove, and restart Outlook.

If the menu only shows View details, a Microsoft admin deployed the add-in. Remove it in Microsoft 365 as described above.
