    When AutoSave is enabled in Excel with either OneDrive or SharePoint, VBA/COM's

    local path from the URL, SharePoint allows to define the "Site name" and "Site

    name contains spaces, they will be stripped out from the URL and (2) you can sync a
    subfolder directly (this, at least, works when you have a single folder at the
    SharePoint's Document root), which results in skipping a folder level locally when
