Last year, Microsoft promised to leave Sunrise on the market "until its features are full integrated into Outlook." However, a lot of the coolest functions, like integration with social media and productivity apps, and "interesting calendars," have yet to appear in Outlook. The app was supposed to be shut down yesterday, but if you already have it on iOS or Android, you can continue using it for now. However, "once [the extra] features are released, the Sunrise app will officially be shut down," it said.
