title: iCal file doesn't import VALARM alerts into outlook as Internet Calendar
body: <p>If I download my generated ICS file and import into Outlook as as a file (essentially just creating a snapshot) then the VALARM I have set works correctly.  </p>
  
  <p>What I want is a ical feed that will synchronize with the server.  So when I create an Internet Calendar (Add/Open Calendar -> From Internet) using my ICS file URL all the events are created correctly and synchronizing works, but the VALARM is ignored and not set</p>

  <p>Am I doing something wrong or is VALARM not supported for internet calendars in outlook?  When I do this in Thunderbird w/ Lightning plug-in then it works great.  So I'm assuming there is some MS specific formatting I'm missing?</p>
  
  <p>I am using Outlook 2016 for my testing.  I read that some people have success with logging into Office365 and importing calendars from the dashboard but this did not work for me either.  I have tried formatting my URL with both <code>http://</code> and <code>webcal://</code></p>
