  2. Hi Christian,

    please try to download a copy and delete existing one, and add the downloaded one again

  3. My challenge is that, when I check out a document from document library. The message that normal popups saying "You are about to check out: Name....xx, From:...xx, Use my local drafts folder " does not show up.
