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.
Here are the steps to re-enabling your disabled add-in:
- In Outlook, click on "File>Options>Add-Ins>Go..."
2. Once you click "Go..." make sure Covideo for Outlook is checked. Click "Ok" when done.
If you would like to prevent the add-in from disabling itself again in the future, you can place it in the "Always Enable" list.
When using Covideo for Outlook, users can force the add-in to always be enabled.
On the File tab, click <Slow and Disabled COM Add-ins>.
You'll see a list of add-ins. Click Always enable this add-in.
3. Restart Outlook for all of the changes to take place.
