I have used Exel for many years and never experienced this problem before.
One day I opened a file and it was okay; I could undo and redo with no
problem. I had emailed the spreadsheet to a friends computer, did some work,
saved it and sent it back to myself. When I opened it again the undo/redo
functions didn't work. When I first put the number in the cell before I hit
enter you can undo what you entered, but once you hit enter the icons turn
gray and don't work. I have researched every where I can think of, but still
cannot solve this problem. Your help will be greatly appreciated.
 
Saved from a previous post:

You could be using a workbook that has event macros. Most macros that do
anything destroy the undo/redo stack.

I'd start excel in safe mode:
close excel
Windows start button|Run
type:
excel /safe
and do a few things to see if undo/redo work.

If they work ok, then you'll have to find the workbook that contains the macro
that's doing the damage.

Another thing that could have gone wrong is that a registry entry was tweaked.

There's a setting in the windows registry that tells excel how many undo levels
to keep track of--maybe it was set to 0.
