Issue: How to Fix Mail & Calendar Update Error Code 0x80073B0F on Windows 10?

I’m running Windows 10 from the start. Despite some minor failures, I worked fine all the time. However, recently I’ve started confronting with an error code 0x80073B0F on Windows Store when trying to update Mail & Calendar. After I attempted to run the update, the app became unusable and I can’t even start it. I’ve rebooted the system, but the app still doesn’t work. Don’t know what else I can do. Any help would be appreciated.
