Hi @Ioana M
Welcome to Q&A forum~
As Viorel suggested, could you please tell us which version of Office you are using?
Does this issue occur with other Office apps, such as Word?
The AutoSave button is not available in some Office apps, such as Office LTSC 2021, Office 2019.
Please share us with screenshots of the Quick Access Toolbar in Excel and the Product Information in "Account".
