  Microsoft.Office.Interop.Outlook error - The file filename.ics is not a valid Internet Calendar f...

  Nov 08, 2012 11:47 PM|LINK

  I'm trying to utilize the contents of an Outlook 2010 calendar on a web app. For that I set up a WebDAV enabled website on a IIS 7.5/Windows 2008 R2 machine. From Outlook 2010, I published the calendar to the website I set up, and that resulted in a new .ics file on the website folder.

  Now, to read/parse the contents of the file, I copied that file over to my VS 2012 machine, which is the same machine where Outlook is installed. I used this example to parse the file: http://msdn.microsoft.com/en-us/library/office/bb644609%28v=office.12%29.aspx

  When I use this code in the example (modified a little bit), I get 2 exceptions, one on OpenSharedItem which says Operation Failed, and another on OpenSharedFolder, which says that the file is not a valid internet calendar file.

   

  string fileName = "filename.ics";
  
  if (!File.Exists(fileName))
      Console.WriteLine("File Does NOT Exist");
  else
      Console.WriteLine("File Exists");
  
  // First try to open the icalendar file as an appointment
  // (not a calendar folder).
  object item = null;
  try
  {
      Application a = new Application();
  
      item = a.Session.OpenSharedItem(fileName);
      Console.WriteLine("open shared item");
  }
  catch(System.Exception e)//gets thrown
  {
      Console.WriteLine("Open shared item failed");
      Console.WriteLine(e.Message + e.StackTrace);
  }
  
  if (item != null)
  {
      Console.WriteLine("item not null");
  
      // Display the item
      OutlookItem olItem = new OutlookItem(item);
      olItem.Display();
      return;
  }
  
  // If unsucessful in opening it as an item,
  // try opening it as a folder
  Outlook.Folder importedFolder = null;
  try
  {
      Application a = new Application();
      importedFolder = a.Session.OpenSharedFolder(fileName, Type.Missing, Type.Missing, Type.Missing) as Outlook.Folder;
      Console.WriteLine("open shared folder");
  }
  catch (System.Exception e)//gets thrown
  {
      Console.WriteLine("Open shared folder failed");
      Console.WriteLine(e.Message + e.StackTrace);
  }
  
  // If sucessful, open the folder in a new explorer window
  if (importedFolder != null)
  {
      //never reached
  }
