I have latest updates for Office 2011 and latest OSX El Capitan 10.11.1 version, however as of today my Outlook 2011 no longer opens.

When I click on the icon in the Dock, a dot appears below the 'O' and the gold 'Outlook 2011' banner opens briefly on the page.  then the banner disappears and so does the dot under the 'O'

any ideas what this could be?

thanks in advance
