Deploy the Add-In in Microsoft

Deploying the add-in involves setting up user groups in Azure and giving a limited set of users access to the add-in.

Giving access to only a few users lets you test that the add-in is working properly and troubleshoot any issues that arise. Keep in mind that deployment and testing can be an iterative process.

1. Sign in to the Microsoft 365 portal: https://admin.microsoft.com/.

2. Select Settings > Integrated apps.

3. Click Upload custom apps.

4. In the Deploy New App page upload apps page:

   1. For App type, select Office Add-in.

   2. Select Upload manifest file (.xml) from device, click Choose File and select the manifest file you downloaded earlier in Set Up the Integration in Application Composer.

   3. After you upload the file, click Next.

5. On the Add users page:

   1. Specify whether this is a test deployment.
   2. Under Assign users, specify who gets the add-in.
   3. Click Next.

6. On the Accept permission requests page, review the permissions and click Next.

7. Click Finish Deployment.

The application confirms that the deployment is complete and that the add-in appears on the apps page.

It can take several hours for the deployed add-in to appear on a user's Outlook ribbon. Users who are added to the group are automatically assigned the add-in. And, when users are removed, they lose access to the add-in.
