autosave changed in excel

jheintze , not only in Excel, that's for entire Office. In general AutoSave (not saving AutoRecover versions) works only with OneDrive or Sharepoint. If yo don't like, you may ignore that suggestion.

I have a similar issue, not sure if it's what you have. If I open a onedrive for business document from the web browser the office app (excel, word..) knows the document is from onedrive and enables autosave, but if I open it from the onedrive folder in the MS explorer (that is a Onedrive for business synchronized folder) it does not recognize it as being part of Onedrive an autosave is disabled (if I try to enable it it tries to upload a new copy).

I have last version of office and onedrive client:

excel 1904 (build 11601.20144 Click-to-Run)

onedrive 2019 (19.042.0304.0007)

Thanks,
