I have an excel file that won't let me save changes because it is Read Only. If I say save anyway, it creates a Copy of the file, then doesn't let me save that either because it is read-only. Sometimes it tells me that there is another copy open (there isn't). The file properties do not show the file as read only.

I am using Office 2007 with W7. I also tried on Office 2003 with W7, same thing. Driving me crazy.

Has the workbook been marked as final? The status property will show marked as final. You can remove that status by going to the Office button>Prepare>Mark As Final. You might want to check there. If it has been marked as final, it will show read-only up on the title bar.

The problem doesn't come up consistently, so I haven't had a chance to try the solution. Thanks for answering, I had given up. I will try at first opportunity.
