STATUS_CS_ENCRYPTION_NEW_ENCRYPTED_FILE
A new remote encrypted file needs its EFS metadata stream
The client is creating a file that is intended to be EFS-protected, and the server requires the associated encrypted-file metadata before ordinary data transfer can continue. The public message refers to the EFS metadata stream used to describe encryption state and key information.
The client should continue through the CSE protocol and provide the metadata expected for the new file. Creating an empty normal file first and trying to retrofit raw encrypted data later can leave a mismatched object. Confirm that the destination file system and server support the full workflow.
What to inspect
- Capture the create disposition and the CSE operation that requested metadata.
- Verify destination EFS capability and user or recovery certificates.
- Abort and remove incomplete output if metadata creation cannot finish atomically.
