On my iPhone, the Calendar app gives me a unified view of all my calendars: personal iCloud, family iCloud, google calendar that I share with someone and the Exchange calendar from work. I've seen a similar setup on Android.
I've tried doing the same thing on my desktop PC (Windows 8.1) in Outlook and it doesn't really work well. For one, I can't seem to edit either iCloud or google calendars - it only gives me a read-only view. I've also tried Thunderbird and that works even worse
Does a Windows application exists that replicates the unified calendar view like I have on my phone?
P.S. I found a method that works, thought it is really cumbersome. I've installed a MacOS into a virtual machine (lots of tutorials on YouTube), and I am using the Calendar app on it. It supports everything that the mobile app supports and is nice to look at as well.
