Campus Mailing Lists, Getting Outlook to recognize 3rd Party Calendar Events

This document describes the expected behavior of calendar events sent a Campus Mailing List from Outlook, Gmail, Yahoo and Hotmail.

There is a registry key a user can set to make Outlook recognize 3rd party / unknown calendar events.   When the key is set to 1 the Outlook will attempt to interpret the 3rd party calendar format so you can accept or reject it.   By default the key doesn't exist so when the key is set to 0 Outlook will not accept meetings sent by 3rd parties.   


Key: HKEY_CURRENT_USER\Software\Microsoft\Office\<version>\Options\Calendar 
Value name: ExtractOrganizedMeetings
Value type: REG_DWORD
Value: 1


Below are appropriate registry setting files for the different versions of Outlook.  Simply download the *.reg file for your version of Outlook, double click it and Windows will create the key and enable the ExtractOrganizedMeetings feature.

There are known side effects of ExtractOrganizedMeetings key.  These include:

  1. When booking a room, the meeting is not automatically declined when your time conflicts with another meeting already scheduled.  Double click on the room to see its availability.
  2. A meeting created by a delegate appears on the delegate's calendar even-though the delegate was not invited.
  3. Updates to a single instance of a reoccurring meeting do not get reflected on the delegate's calendar.
