Office365 Autoupdate on Mac

Last week I had an issue with Autoupdate on Microsoft365 where OneNote failed to update, other app were fine. I tried selecting just this app and updating it but got a download error. Autoupdate indicates "some apps have encountered errors" and retrying just repeats the download error. I've tried machine based fixes but none have worked and I suspect it's something else as I have a Mac mini and MacBook doing the same along with my wife who has a Mac desktop. The issue is still the same a week on.
