It is my understanding when you create a meeting you default as the owner and are added as an attendee.

When creating a calendar meeting are you and your users using the scheduling assistant?

Check to see if your name is the owner or the user you are creating on behalf of is listed. If the other user is listed add yourself ( hence the user creating the meeting) as an attendee. The meeting will then show on the personal calendar.

Update us so we can further assist.
