How can I share UserProperties between users?

My Add-In stores specific values in the UserProperties collection of the MeetingItem as well as in the associated AppointmentItem.

These values are displayed in a custom form in the Inspector Window.


I send a meeting invitation out to Invitee1 and Invitee2

They both accept, and Invitee1 updates the custom form in the Inspector Window.
He will always be able to see this information.

When Invitee2 opens the appointment in his calendar, I would like him to see this information as well.

As far as I can tell, when Invitee1 updates the Appointment in his calendar, the only thing updated is his copy of the appointment for this meeting and no one else's. 

I guess I'm looking for some shared area that I can add information to.

Hello German,

You are on the right avenue. A separate item is updated in the invitee1's calendar. I'd suggest developing a web service where you can request all the required information for other users. But in that case they should have your add-in installed.

Thanks Eugene,  we already have a web service and we were thinking that maybe this would be a good place to have this information.

You are right on the money as usual.
