According to Microsoft, if I store a file (Word or Excel) on my iPad, I can open, edit and save that document locally when offline. However when I try to do this, I get a message across the top of the document asking me to sign in if I want to edit. So working offline is impossible despite assurances to the contrary.
Hi @PaulAus1957, Even for being able to edit and save locally you will have to sign in first, and it is a one-time process. Once you are signed in in the Microsoft word or excel app on your iPad then you can edit and save locally anytime offline.
