I have been using Microsoft Outlook 2013 (32bit) for almost a year and it crashes and freezes occasionally. When I compose a new email or reply back to an email and finish writing the body text, as soon as I click on "send" button it stops responding and I have to close Outlook and restart it. It happens almost 25% of the time. I have never had this problem with previous versions of Microsoft Outlook! I have had this problem on three Toshiba laptops and Ultrabook with Windows 8 Professional (64 bit).
