After MCN updated Hotmail to Outlook, we have been unable to attach documents.    When attaching the document to an e-mail, the document acts like it's going to attached but then we get an error message, "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available".  I've tried all your suggestions but still not working.  Our Sliverlight is up to date and I have tried clearing my browser many times.  I am currently on a PC, my browser is IE10, Window 7 professional edition.  Is there a setting not turn on?  I don't know what steps to try next. HELP.
