Outlook Mac 2011: Can No longer access “Accounts”

I have been having MANY problems with Outlook for a while, many of which have been detailed in previous posts. 

After it repeatedly asking me to 'verify' certain (non-essential) email addresses repeatedly, I decided to just delete them. 

However, when I try to access "Accounts" it just crashes. 

If I try through Preferences it just hangs, nothing happens. 

If i try through the toolbar it creates a white square where ostensibly the account list would be. 

i have done a clean install of Office for Home/Business 2011 and rebuilt the Identity at least 5x. 

any other ideas? 

Thank you
