The Microsoft Office suite’s document cache settings can be managed in the Office Upload Center. From the Upload Center Settings menu, you can delete all cache files and configure how Office handles cached files in the future. For example, you can configure the document cache settings to “age out” and automatically delete old cached documents from local storage. Original documents are stored in the cloud and unaffected by the removal of items from the local document cache. The cache cleaning process differs a bit for Office RT.
