Look at all the entries in your HJT log starting with 04 or 23. They are the ones that run at startup. I can't see any that are calling Outlook directly but it may be that one of the others is opening itself and then running Outlook afterwards. For example, you have Norton AV on board and perhaps that is opening Outlook so it can scan for viruses in your emails before you go looking at your mail.
The first thing I would try is to open your PC in Safe Mode and see if Outlook opens under that. If it does you are going to have to disable the 04 entries one at a time and reboot to try and track down the guilty party.
There are also some entries in your log that need further investigation. For example
I would be inclined to post a new log in the HJT section and seek some expert advice.

Well, if forty-eight million, two hundred thousand, seven hundred and one people died I'd be Queen.
