Until a few days ago the AutoSave button was available and AutoSave worked fine in both Word and Excel (providing, of course, the files were in the correct format). Then, the button was there but greyed out, despite anything I tried. For some reason, Word would only save files to my PC although most of them were eventually synced with OneDrive.
I then uninstalled and reinstalled Office 365 (64-bit version). Now, the AutoSave button has disappeared (not just greyed out) in both Word and Excel. Files are definitely being saved to OneDrive. They are also set to sync to my hard drive (confusingly, to a folder called SkyDrive, but I can't find a way to change the name). I can see no reason why AutoSave should not be available and working as it did before. The only way I can get it to work now is to edit or create files on my iPad - but that is not a long term solution.
Can anyone help?
