title: Analyzing Outlook HANG dump (with GoogleCalendarSync add-in installed)
body: <p>Since I started using outlook with GoogleCalendarSync i'm experiencing hangs every once in awhile. 
  I used ADPlus to create a hang dump of the process (using <code>adplus -hang -pn outlook.exe -o c:\dumps</code>). 
  When I read the dump via WinDBG I use the command <code>!analyze -v -hang</code>, but I can't figure out what exactly went wrong.
  The output of the command is:</p>
