Close function not working right

[Dan Wilson]

Good day. I am running Excel out of Office 365 on Windows10. I have two workbooks that are basically the same. One is for 2018 and the other is a copy getting ready for 2019. After doing some editing, the older version is now closing without asking me if I want to save it or not. The other one is still closing correctly. I have been searching through the options function, but I don't think I changed anything that would cause this problem. Any help is appreciated.
Thanks, Danno...

Good day all. I have found the problem for this issue. The workbook was saved in the OneDrive folder. Apparently, workbooks saved in that folder do not allow Excel to work properly. After moving the workbook to my Documents folder on This PC, all is well. If anyone has an explanation, I would love to read it. OneDrive has been a real pain in the butt for me and I don't always remember it.
Thanks to all who read this thread.
