Have you any idea why office application like Excel or Word shows different name in version history than SP version history? This is version history of some Excel file viewed through SP GUI:
... and the same file viewed through MS Excel app.
From where is the atribute comes from or what Excel read after my file was open? And to make it even harder, what should I do, if the files was digitally signed and MS Word displays warning message that the integrity of this file was broken and its untrusted now because of different names?
Affected files was deployed through CD job and their versions through PowerShell script under system account (or Kamil's, used on image above). In fact, all moved versions of all Office documents change their ownership, but we need to solve this situation mainly for the digitally signed ones.
... beside that, how can we move document versions after CD jobs in right way? PS damage ownership, moving one by one is not a solution, for example this affected place contains thousand of files, migration tool is not the solution, because it cause all problems, that we have now.
