Invalid Value for Registry MP4: A Common Error in SharePoint Online

When trying to open or upload files in SharePoint Online, users may encounter an error message that reads 'invalid value for registry mp4.' This issue is often caused by a limit set on the Web client service responsible for opening files through file explorer or mapped network drives. In some cases, this error can also occur when uploading large files exceeding the maximum limit configured in Central Administration.

One probable cause of this error is a file sharing or file permissions problem. When users try to upload a file larger than the allowed size, they may encounter an error message stating that the file size exceeds the limit and cannot be saved. Additionally, opening the file directly can also result in the same 'Could not open file' error.

Error 0x800700DF is often associated with this issue, indicating that the file size exceeds the limit allowed and cannot be saved. This error may occur when copying a file from SharePoint Online through file explorer, resulting in an error message stating 'An unexpected error is keeping you from copying the folder.'

To resolve this issue, it's recommended to check the maximum upload size configured in Central Administration and adjust it if necessary. Additionally, ensuring proper file sharing and permissions can also help prevent this error from occurring. By understanding the root cause of this issue, users can take steps to overcome the 'invalid value for registry mp4' error and successfully open or upload files in SharePoint Online.
