For some time have had the following problem,

the 'save' and 'save as' options to save as a .docx file shows progress bar reaching about 75% when another screen pops up requesting another 'save'*operation. Doing this brings another box saying 'Error has accord while saving'. A circle follows.

Have tried repairing Office 365 through the Control Panel, both quick and full repair, but there is no improvement. Possible to save document as a .pdf file but, of course, opening it again in Word changes the font and photo positions.

In seeking a solution, have tried to boot in safe mode but am told win word/safe file does not exist.

Would appreciate some help please. Am running W7Pro

What are you doing to open in safe mode?

Hold the Ctrl key down when starting Word. Then release the Ctrl key. A message should pop up asking if you want to start Word in safe mode.

Thanks Charles.

Word opens in safe mode with that key, and the save function is working.
Will continue working in safe mode. But, a whole hours work has been lost because Save could not be used yesterday.
