Do you have an icon that is just "Scheduling"? Possibly located between "Appointment" and "Meeting Notes".
Or a small calendar icon presented as a small bar with three row of five squares below?
On your Calendar Page do you have a Manage Calendars section with "Open Calendar" and "Calendar Groups"?
However, still struggling with the details as I think we have different Outlook setups.....
That said I also did some research and found this link:

May be the solution that works for you.
FYI this is what I googled: "Schedule Outlook Meeting via email without myself attending"
There are other solutions and it may be Outlook version specific....
Please post if I am still missing something.
