I purchased office 2010 home and student then decided I really wanted outlook back and purchased it separately. This was after running the Ofiice 2010 beta professional for some time. However after de-installing all the beta versions, when I re-install outlook 2010 it still picks up the old version of my account information and would not let me delete it as an account, which I wanted to to as I screwed it up the first time. it is a @live.com account so I removed the hotmail plug in, uninstalled and re-installed and it still picked it up, so in desperation I uninstalled deleted the outlook folders and re-installed and now it just tells me that it cannot find the pst file for my old account and shuts down. How do I ensure that the next install I do does a clean install as if no version of outlook had ever been on the machine?
