A user has a problem with her Excel file where changes are not saved (or seem to be anyway) even though she has "checked it in" ...
"... OK, I now see the checkout option.
So I checked it out, then I had to select edit,
I made a change and saved and closed. It didn’t ask if I wanted to check it in.
I selected check in and entered the comment “test”
It’s now showing checked it BUT the change I made is not captured. That is, it didn’t process my update!"
Any ideas... I think it is only for this user which is also a member of our "Sharepoint Contributors" AD group. No one else has this problem.
