Unfortunately we have over 4000 .ics files that we need to import into Outlook 2013. Each file is one event. What's the best way for doing this?

This question came from our site for system and network administrators.

  • You realize that once imported 4000 calendars will slow Outlook down right? Are you sure you want to do that? – Ramhound Feb 18 '15 at 19:05
  • ICS is just an event. You can import events into one calendar. – Sun Feb 18 '15 at 20:38

Given that the .ICS (or iCals) format is a textfile, I would merge all files into one .ICS file and import that one file.

Just open your .ics file and look at the layout. You can also read about it here: http://en.wikipedia.org/wiki/ICalendar

The wikipedia article is too long to quote, so thats why I haven't done that.

    This is when installing cygwin and using cat *.ics > all_ics.txt is useful. Then rename all_ics.txt to all.ics to perform the event import. – Sun Feb 18 '15 at 20:39
  • That doesn't seem to work in Outlook 2010 – Ilan Dec 17 '15 at 14:28
  • Well - actually it works if you manually edit out all the interim BEGIN:VCALENDAR & END:VCALENDAR as per productforums.google.com/forum/?hl=en#!msg/calendar/KJ_rH90hIDA/… – Ilan Dec 17 '15 at 14:35
