Error reading public folder events with Exchange Webservices

Copper Contributor

I'm not sure this is the right place to ask this question, but I'm getting quite desperate. 

I'm trying to develop a c# application that uses Exchange Webservices to read a public folder calendar events. 
I'm authenticating using App-only as per microsoft documentation and I am able to obtain an access token.

I Created the a public folder calendar in the Exchange admin center, created a test event on it, and enabled it's email that came out something like this:

CalendarName   @


while trying to get the public folder events, i get this error: "The SMTP address has no mailbox associated with it."

I created a public folder mailbox, but I cannot find anywhere on the exchange admin center where to associate public folder mailboxes to public folder.


CalendarView calendarView = new CalendarView(startDate, endDate)
PropertySet = new PropertySet(

calendarFolderId = new FolderId(WellKnownFolderName.Calendar, CalendarConfig.CalendarEmail);

var appointments = await ewsClient.FindItems(calendarFolderId, string.Empty, calendarView);
