Excel Data Loss After Office Update

Hi,

A user updated Office 365 for Mac to 16.109.3 (26053122). After the update, an Excel file saved locally on Desktop lost many recent edits. Autosave and OneDrive back up were not enabled. Checked the AutoRecover folder (/Users/<username>/Library/Containers/[com.microsoft].Excel/Data/Library/Application Support/Microsoft) — no recovery file found.

Is there any known issue with this update causing local Excel files to lose data? And is there any other way to recover the file in this scenario?

Thanks

    Hi GoodPig

    Thank you for reaching out to the Microsoft Q&A Forum. 

    Based on my research, I could not find any information indicating that Excel for Mac version 16.109.3 is known to cause locally saved Excel files to lose previously saved edits after an Office update. 

    If the file was stored locally and the recent changes are no longer present in the current version of the file, and no AutoRecover files were found, then unfortunately those missing edits may not be recoverable. 

    Thank you for your understanding.
