Yes, you could use either Name or Key. Key is generally what you use in code and Name is for when you want to display some other name to the user.

- In the Unassigned calendar create a single entry (do not allow any additional entries) that the user can drag up/down/resize to find a time that works with the owners schedule listed in the remaining calendars.

I'm not really sure what you are asking here. There's no built-in functionality for this kind trial-and-error scheduling. It might be possible by handling a whole bunch of events, but since I don't know exactly what behavior you want, I'm not sure how to assist you with this. It would probably be tremendously complicated.

- As the user drags the appointment within the unassigned calendar can we sync a selection/highlight within the remaining calendars - So that there is a visual comparison on how any given block of time fits on the remaining calendars?

Again, there is no built-in way to do this. You might be able to use a DrawFilter to draw something in the other days that matches what you are doing in the Unassigned owner, but this would be very complicated and it's probably not something we could handle through support. That would be more like a consulting job.

- Make the remaining calendars read-only

You mean the remaining owners? I think you answered this in your second post. I don't know if PropertyChanged is really a good way to go here. I would probably approach this by looking at the events of the UltraDayView and the CalendarInfo. You could handle events like BeforeDisplayAppointmentDialog, BeforeAppointmentEdited, BeforeAppointmentResized, etc. and cancel the event based on the owner.

Style Question - I only see a BarColor that can be set which only sets the left most border color of the appointment block... How can I set the entire color of the appointment block?

Use the Appearance property on the Appointment for this. So in my sample, you could do something like:

appt = calendarInfo.Appointments.Add(startDateTime, "Appt2");

appt.Owner = ownerB;
appt.BarColor = Color.Red;
appt.Appearance.BackColor = Color.Purple;
appt.Appearance.BackGradientStyle = Infragistics.Win.GradientStyle.None;

I was able to tie into the SubObjectPropChanged event and use that to sync appoints that I have a handle on across all calendars. I have set the Locked property of the other events so that the user can only drag the proposed appointment and get full sync across calendars to see how it fits.

This is very good, thank you... 

Can you help me with the following:

- The first column will be named Proposed Appointment, can I just set the Unassigned.Owner.Key/Name properties for this?

- In the Unassigned calendar create a single entry (do not allow any additional entries) that the user can drag up/down/resize to find a time that works with the owners schedule listed in the remaining calendars.

Hi Jesse,

You can get something pretty close to this by using the UltraDayView and creating Owners in your CalendarInfo. I am attaching a small sample project here that demonstrates this.
