Easiest way to time bomb a workbook

Hello,

I have a workbook I use to track some employee information, off time, etc. This is a small Company with employees on contracts around the world. I update the workbook weekly and send it out to the employees, for informational purposes only.

To avoid having multiple copies floating around, I want to time bomb the workbook before I send it out.

Ideally I want it to delete itself after a period of 7 days from the date I select when I send it out.

I have decent knowledge of excel but I am fairly clueless when it comes to VBA.

Any help is much appreciated.

Thanks,

R
