At this time we do not have a workaround for the Microsoft store version of Outlook rather than the Click to Run version as this version is not compatible with the tool. This is caused by the difference in installation method and build in Microsoft. In order for the Add-in to work as designed or expected you would need to have the Click to Run version of Outlook. You can find more information about this here.
