Storing documents locally or in cloud services like OneDrive from within Microsoft Teams
Hi Jamie,
Sorry for the inconvenience caused at your end.
As per the description provided, we understand the concern facing at the user end and since you mentioned “AutoSave is turned on”, I believe you are opening the Excel file in the Excel application. Since the problem is one with specific user, please ask the problematic user to try the following and check the behavior:
a. Close the Excel files> Remove the Excel file from the Recent tab> Quit Excel application.
b. Open the File Explorer> Go to C:\Users\username\AppData\Local\Microsoft\Office\16.0\OfficeFileCache> Delete all content in that folder.
c. Re-open the Excel application> Open the problematic Excel file> Check whether file works without any problem.
If still persist, please check whether user is using the latest version of the Excel application.
Best Regards,
Chitrahaas
