title: Is there any way to know if Outlook 2010 has new email with C#
body: <p>I'm curious if such is possible with .NET. I wrote a small C# Windows GUI app and I was wondering if there's any way to "tap into" Microsoft Outlook 2010 and check if it has any new (unopened) emails present? Normally such condition will be indicated by the presence of an envelope icon on the system tray:</p>
