Word document not saving changes

[Davee22]

Hi,

My girlfriend uses company Macbook for school related work as well. And today she was just working in one of the word document in desktop application, adding new text and continously saving the changes made. But suddenly, when she have just opened the document again tonight, all the change she made in the morning today are not present in the word document and the document says, that last change was made the day before.
Is there a way to recover this lost progress, while not having autosave on? And could this be caused by some issues related to updating the Office software? As she kept receiving an error, when she tried to open the document, something like "User doesn't have privilige to open this File" despite giving the access. She proceed to restart the Mac and then this message disappeared and she was able to open the word document, but then the initial problem, discribed above appeard.

Thank you,
David

If the document was being saved to a folder that is synchronized with OneDrive, right click on the file in OneDrive and then on Version History and see if one of the earlier versions contains the recent edits.

Unfortunately it wasn't synchronized with Onedrive.
