title: Using ExchangeService to Add Appointment Occurances
body: <p>The target is someone's Exchange Calendar (2007). I want to add a simple "Appointment Occurance" to someone's calendar. This code works (I am using the Microsoft.Exchange.WebServices.dll):</p>
  
  <pre><code>service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
  service.Credentials = new NetworkCredential("supervisor", "password", "DOMAIN.COM");
  service.AutodiscoverUrl("&lt;employee@domain.com&gt;", ValidateRedirectionUrlCallback);
  appt = new Appointment(service);
  appt.Subject = "&lt;subject&gt;";
  appt.Body = "&lt;Body Text&gt;";
  appt.Start = _DateFrom;
  appt.End = _DateTo;
  appt.Sensitivity = Sensitivity.Private;
  appt.Save(WellKnownFolderName.Calendar);
  </code></pre>
  
  <p>However, there are problems with this code:</p>
  
  <ol>
  <li>The appointment target is the employee. When adding the appointment, the appointment shows up for the employee (yay!) but also for the supervisor (boo!). Am I supposed to use the employee's credentials? If so, what if I do not have access to that - only the supervisors, am I out of the game already?</li>
  <li>The appointment shows up in Outlook as a "Meeting Appointment" and not and "Appointment Occurrence". So, the box to input meeting attendees is showing (with no one in it of course), and is irrelevant in my scenario.</li>
  <li>appt.Body does not respond at all to Environment.NewLine or "\r\n" - I haven't tried HTML yet.</li>
  </ol>
