问题 I would like to create an Appointment through EWS with a compressed RTF body instead of the default HTML format due to several bugs w/ Exchange around HTML formatted appointment bodies. The code I am using looks similar to that below: var appointment = new Appointment(exchangeService); ... string html = // html body string compressedRtf = // converted using Microsoft.Exchange.Data.TextConverters ... var epd = new ExtendedPropertyDefinition(0x1009, MapiPropertyType.Binary); appointment

问题 so when clicking the submit button in my application to create appointment on outlook calling the function SendOutLookAppointment() i get the error on this line appointment.Save(); The request failed. The remote name could not be resolved:'servername' public static void SendOutLookAppointment() { ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010); service.UseDefaultCredentials = false; service.Credentials = new NetworkCredential("admin@test.com.", "password"); service

问题 var message = EmailMessage.Bind(exchangeService, itemid, new PropertySet( ItemSchema.Attachments)); exchangeService.TraceListener=new TraceListener(); exchangeService.TraceEnabled = true; message.Load(new PropertySet(ItemSchema.MimeContent)); // Getting exception here. // File.WriteAllBytes("email.eml", message.MimeContent.Content); I am getting the below exception when trying to load the mime content.

Original Post below: I have a piece of code that moves items from one folder to another using the EWS API and C#. This is not a duplicate to What is a NullReferenceException, and how do I fix it? as this issue seems to occur within

问题 Trying to create a calendar event in exchange using the Microsoft.Exchange.WebServices.Data.Appointment. Everything works fine until I set the IsOnlineMeeting property to True. This results in the error "Set action is invalid for Property". In the Appointment object this property is marked as "settable".

I'm using powershell version 5 with the Exchange 2010 management console module (EWS).
