Microsoft Plugin 2011 Missing on Mac | 2011 Outlook + IMAP email won’t sync outgoing

Help, my GoDaddy IMAP email can not be sent from my 2011 Outlook.  (It can be received, but not sent. Other emails can be both sent and received.  When I checked with GoDaddy, everything is running ok from their side. It will sync properly to my iPhone, just not my Outlook.)

When I researched online and through my applications for a solution, I noticed that my Microsoft PlugIn is missing.  When I tried to update my Outlook, I was notified that "the update can't be installed because a version of the software required to install the update was not found on this volume."  See below for screen grabs.  What should I do???
