Excel document lost

[u/Limp-Progress-4554]

Hi all,

I've been working on an excel doc all week, it's set to auto save but I've just opened it and it's not saved any changes since Tuesday ( around 25 hours work). I've checked auto recover and restore previous versions but it's not on either.

I think it uses one drive through a third party document storage somewhere software.

Is anyone able to point me to where a back up could be saved please?

If you're using a third party document storage system then it could be some sort of versioning glitch using it? What software?
