It is common with Microsoft Outlook meetings that the organizer will view the tracking tab in Outlook and see a users response as ‘none’.  They contact the user and that user explains that they accepted the meeting.  The organizer will then contact IT because Outlook is “broken” and not updating the meeting responses.


If the attendees accept the meeting and choose to not send a response, it is expected that the tracking tab is not updated with their response.  This situation is usually the cause!

Other Possible Causes the tracking tab displays none:

The meeting responses are being processed by another client, device, or third-party application. These may include, but are not limited to, the following.

  • Outlook add-ins
  • Mail archiving program
  • Devices that use Collaboration Data Objects (CDO) to synchronize with your Microsoft Exchange mailbox or calendar
  • Devices that use Microsoft Exchange ActiveSync (EAS) to synchronize with your mailbox or calendar
