I had a problem where my SkyDrive was not reflecting tagged people in photographs that I was only able to resolve by re-uploading pictures after tagging them. The problem now is that my SkyDrive has become completely corrupted. There are some duplicate files and folders and I've attempted so many troubleshooting steps that now everything is completely messed up. Fortunately I have a local backup of all my data. I'd like to COMPLETELY reset my SkyDrive account both online and offline and then re-upload everything from scratch. How do I do that?
