Log in with an account with the appropriate permissions on admin.microsoft.com.
Under Settings, go to “Integrated apps”.
- Choose the “Add-ins” option.
- Deploy a new add-in.
- Choose the “Deploy custom add-in” option.
- Click “Choose file”.
- Add the manifest.
- Select the desired option for rolling out the add-in.
- Select the deployment method.
There are three deployment methods. As FileCap, we recommend choosing the optional method. When the optional method is used, it is much easier to troubleshoot add-in issues for an individual user.
- Click Deploy.
Due to a Microsoft synchronization delay, it can take up to 72 hours before the add-in appears in users’ ribbons; users may need to restart Outlook.
