Hi guys and gals,

How do you set up a workbook so that it has an expiry date?

I have a spreadsheet that others would like to use. I am happy for them to use it, but don't want them to let someone else (not on a shared network or anything). So I thought that I could set it so that it would expire in a month or 2 and I could send them a fresh copy.

I know that this can be done, but have no idea how to do it.


Any help please?
