How To Manually Create Outlook Calendar Appointments

Feb 08, 2006 • One minute to read

Here’s a gem from David Goodhand, a Microsoft vet that arguably taught me everything I needed to know about giving technical presentations on how to manually create Outlook Calendar appointments.

Copy/Pasted from David’s email

  1. If you’re try to write an appt directly into someone’s Exchange-based calendar, then use the Exchange CDO object model.
  2. If you are trying to generate an appt that the user can click on and add to their calendar, look into the .VCS (vCalendar) file format. For example, look up an item on ebay and click the click “Add to Calendar”. The server generates a .VCS file which the user then clicks on. As the user downloads or opens the .VCS file, Outlook snags it and makes an appt. out of it.

Here’s what an example VCS looks like:

BEGIN:VCALENDAR BEGIN:VEVENT SUMMARY:eBay Reminder: SONY DIRECTV ULTIMATETV W60 HU REMOTE V3.5 DESCRIPTION:The end time for eBay listing number 3061186172 is scheduled to end soon! Click here to go to the page:
