Error 0x00700DE When Downloading File Over 50 MB Using Web Folders
Categories: Errors, Webfolders / WebDAV
Most versions of Windows interpret a Web Folder /WebDAV download of a file over 50MB as a security issue. The likely error message is “error 0x00700DE the file size exceeds the limit allowed and cannot be saved”.
The easiest workaround is to download the file using the My Docs Online Web Client or Desktop App.
A Microsoft support article offers more details and an alternative workaround.
