When sending a meeting request, the meeting appears on attendees’ calendar, but is missing from the organizers calendar. 

This issue occurs when a property on the original calendar item points to the drafts folder. This behavior has also been observed when a meeting item is created, saved, and sent much later. 

This only occurs when the organizer’s calendar is of Type MAPI which is expected for Primary account calendars. Shared Calendars can be Type REST. To confirm the Type, right click on the Calendar folder and select Properties.

We are looking for more examples of user impact to investigate this issue. We are asking impacted users to:

  1. Gather a Fiddler when either creating or updating a meeting in the owner Calendar. For more information on how to gather a Fiddler trace, go to How to run the Fiddler Trace after installing the Microsoft Support and Recovery Assistant.

  2. After the meeting has been created or updated, collect Calendar Diagnostic logs for the meeting. For more information on how to gather Calendar Diagnostic Logs, go to Get-CalendarDiagnosticObjectsSummary.

  3. Open a support case once you have gathered the necessary data and support will assist in analyzing the data.


Use the Outlook web app or new Outlook to create the meeting or send the meeting update.
