Sorry I am a little late here, but it looks like you used the icalendar validator at http://icalendar.org/validator.html. I am the author of that validator and after researching the issue I found a bug with the validator related to your feed. The bug was incorrectly including the blank space after the word "VCALENDAR" to determine the mismatch condition. There was a space after the "BEGIN:VCALENDAR " but not after "END:VCALENDAR", resulting in the incorrect validation error. White space at the end of the line is not an error, so this has been corrected. And you can try re-validating your feed again to see the updated results.

It may also be related to a bug in Exchange 2016:

If you have recurrent events and modify one of the instances, Exchange 2016 delivers invalid iCal data, i.e., the END:VCALENDAR is missing.

See here for my bug report: https://social.technet.microsoft.com/Forums/office/en-US/9952d9ea-6040-46b8-93d7-f163c09acd70/bug-in-ews-invalid-ical-format-if-recurrent-event-modified?forum=exchangesvrdevelopment

The X-ALT-DESC property value is not folded correctly. Whenever a property value has multiple lines, each additional line must be prepended with one whitespace character, like so:

X-PROP:one
 two
 three

Also, your UID property is not on its own line.

your DTSTART:

DTSTART;VALUE=DATE:20160621T000000Z

and your DTEND:

DTEND;VALUE=DATE:20160621T000000Z

have the same values.

RFC5545 specifies

The "DTEND" property for a "VEVENT" calendar component specifies the non-inclusive end of the event.

which means that your event is not-defined. if you wish the even to last one day, just remove the DTEND

Also you specify a VALUE=DATE but give a DATE-TIME. Either change the property to VALUE=DATE-TIME or change the value to be a date:

DTSTART;VALUE=DATE:20160621
