When tracking an appointment in when using the Outlook App w/ server-side sync in D365, there is the option to creat a related activity.  In this case, you can create a Task, Appointment or Phone Call.  It would be great if you could include all activity types, but more specifically, any custom activity types.  This would makes sense b/c if we have a custom activity type, it is most likely something that gets used a lot and its omission from here is unfortunate.Thanks.
