Webdav, Windows 10 11, Office 2016+ cannot save file

Webdav, Windows 10 11, Office 2016+ cannot save file, or rename in TTCM

Steps to reproduce

  1. net use with user and password

    • short and long version, now short over apachehttpproxy url //domain@SSL/DavWWWRooot/remote
    • now mounted as
      net use Z: "https://domain/remote" /user:"me" "pwd"
  2. open file form office

  3. reopen for change - message readonly

  4. Click Save - file is readonly

OR in TotalCommander

  1. copy file to mounted drive
  2. open notepad+, save OK
  3. but cannot rename file: mounted drive cannot working
  4. cloned file cannot be renamed too

Edit file in e.g. Notepad+ working corectly

Expected behaviour

File to be saved, renamed, would be highly anticipated :wink:

Actual behaviour

Save as
