I have a project to modify Calendaring, and send personalized invitations. This bypasses the standard process and works fine, except one thing. The creator of the event can’t use the Owner Actions like View Invitee Status and Send Reminders. These pop-up a message box saying “no valid participants”. But the fields RequiredAttendees and Option Attendees are populated correctly.
I think this problem is coming from the fact that the property WasSent is empty. In standard calendar events, WasSent = 1.
Can anyone out there help me understand how this is set, and if there is any way I can do it in code (trying to update in LS gets back the message that it’s a read-only attribute).
