I have a user that is using Office 2007 Small Business. Up until yesterday morning she could open her documents on our SharePoint Online without issue. Suddenly, however, it is giving her the error seen in the attached picture. I have tried running a repair, fully uninstalling and re-installing Office, and resetting IE back to factory settings. I have tried under my login and my windows profile with the same results. It happens to all Office document types on SharePoint Online. She can open Word, Excel etc documents on her hard drive without issue. <br />
