Hi everyone,
I'm stumped on this one. Hopefully someone can help!
I have a Windows 2008 R2 server that publishes a WebDAV "share" through IIS. The URL for the WebDAV "share" is mapped in Windows explorer on a Windows 7 SP1 client. The client has EFS configured using a self signed certificate.
I have custom properties enabled on the Windows 2008 R2 server as described in the post

Now I can copy EFS encrypted documents (mainly Word 2010, Excel 2010) from the workstation to the WebDAV share and they retain their encryption - however if I attempt to open the documents directly from the WebDAV share, they open as gibberish in Word and Excel respectively. It appears that the documents cannot be decrypted.
However if I manually copy the EFS encrypted documents from the WebDAV share back to the client - then they open fine in their respective applications.
I'm scratching my head as my understanding is that WebDAV uses local encryption/decryption on the client when accessing EFS documents stored on a remote server.
Any help appreciated!
