A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
I had a similar problem with Office365 Excel 2016 yesterday. My Autosave is set to 5 minutes and I have never had a problem with Autosave in the decades I have used Excel.
Yesterday, Excel locked up while I had four spreadsheets open and I was trying to select a field in one spreadsheet. An hour later, Excel was still locked up (spinner was still spinning), so I restarted the computer.
When everything was back up, one Autosave file had been created for each of the four spreadsheets, but the Autosaves were from 4-5 hours prior to the lockup. Even more interesting, it appeared the manual saves I had done on each document over the course of that 4-5 hours were completely gone. Can that even happen?
I lost a lot of data. Very annoyed.
