A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data
Dear Dominique,
Good day! Thank you for posting in Microsoft Community.
Please confirm if I understand the scenario correctly. When you close Excel through Taskbar Preview, the file doesn’t close and remains open.
If my understanding doesn’t match your scenario, please post back and point that.
Generally, if we close a local or new Excel file that contain changes, we are prompted if we want to save the file, and application will not be closed until we choose aa option.
As you mentioned this behavior applied only to Excel, to narrow down the source of this issue, may I know if it happens with all Excel files or the certain ones?
Sincerely,
Igor | Microsoft Community Moderator
