I was working on a new document, got up to make a cup of tea and by the time I returned, the Mac had randomly shut down.
I logged back on and as usual, all the windows open when it shut down reopened, including Word.
Word was just blank (it usually seems to repopulate with what you were working on) and there is no sign of the document I was working on, nor of any Auto recover option.
It's Word For Mac v16.12 running under Office 365.
Any MS gurus have any ideas where my document might have gone?
