Outlook will try to protect the user experience by disabling add-ins that it considers to be misbehaving or if there had been an update. This will cause the add-in to disappear from the toolbar.

Step 1. In Outlook, click on "File>Options>Add-Ins>Go..."
Step 2. Once you click "Go..."
Make sure Covideo for Outlook is checked. Click "Ok" when done.
