Outlook won't start

Windows 10 is becoming more and more popular among users. Month after month, statistics confirm that the number of Windows 10 users increases steadily, reaching 25% last month. With features like Cortana, a revamped start menu and more, Windows 10 has become the favorite OS for many people.

The upgrade procedure is very easy to follow and, pretty much, works on its own. But sometimes things can go wrong and one can run into some very weird problems. One of these problems is losing contacts after upgrading to Windows 10.

After upgrading to Windows 10 from Windows 7 SP1, I have lost all emails, my calendar, and all contact lists.  I use these for my home business.  This is unacceptable.  I am not a computer guru but can find my way around.
