How to completely reset access to google calendar

I have setup google calendar to sync. In google I have two email accounts. When I create an event and invite people the email is forced to come from the wrong email account. I can't change it. So I want to delete my old google account and completely create another one using my true email address. I've done that but the old account is cached somehow using both email addresses so when I use my new email address only the old calendars show up and it does not ask me for a new login. It just logs in directly to the WRONG google account. How can I resolve this. I have tried uninstalling all add-ins and restarting and re-installing. I've also deleted all references, email accounts, calendar accounts, contacts, etc, from the old google account. Nothing works.
