I had a business version of Office 365 at work but then left and the suite remained on my laptop but was deactivated. Later I installed my own business version of Office 365 on the same laptop. But whenever I try to login to my own copy it defaults to the work version but cannot open it and I get a OneDrive error message. I have tried to delete the business copy using the uninstaller but it is persistent and keeps coming back. I have even tried removing inherited permissions to the folder containing OneDrive but the error remains the same. My work copy was installed in another country and I no longer have access to the admin so he can't help me. Any advice on how I can rid myself of the work copy and login to my personal copy of Office 365?
