Hi. I've been using windows live calendar by entering reminders and appointments on my galaxy s4. It was always also accessible through calendar.live.com. last night it was just gone. Online and in the app. Besides legal holidays the calendar is blank on mobile and online . I signed out and back in.  Nothing. Oh the interesting part is that some entries from 2014 and 2015, which I obviously deleted after the date, are visible. I definitely deleted it back then but now those entire are back. Help!!! I need my current entries urgently. I haven't done any updates or even logged in lately. does the calender backup anywhere on mobile or online?
