I have a shared excel document created in 2007. It has 12 sheets (1 for each
month). All the sheets work fine except for August. If you try to edit a
cell or make any changes whatsoever it brings up the normal window saying the
cell you are trying to change is protected and read only. The issue is that
the sheet is not protected in any way that I can see. If you go under the
review tab the option to unprotect is greyed out and I can find no way to
work around this. Any help would be appreciated thanks.
