Exception between C# and Outlook

I have a simple code to open a compose email in Outlook 2013 using C#. It works without any issues when Outlook is not running, but when Outlook is already open I get this exception:

An unhandled exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll

Additional information: Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

Here is my simple code:

        Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();
        Microsoft.Office.Interop.Outlook.MailItem mailItem = app.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);
        mailItem.Subject = "This is the subject";
        mailItem.To = "[email protected]";
        mailItem.Body = "This is the message.";
        mailItem.Display(true);

I also get these from Visual Studio output windows complaining about symbols which I have no idea about!:

Any help is appreciated? Thanks in advance

Most likely this is caused by a difference in security contexts. Is either Outlook or your app running with elevated privileges?
