Hi! Everyone

I don't Know Whether my Question have a Sense or not.

But it is Possible to Expire Excel Sheet on Specific Time or Date.


And Even if I Mail that sheet to any Person and he Open After the Expiry
Time or Date

I want to Show the Message "Unable to Open"


Protected Sheet is not a good Option These Password can be Break Easily


Any Help Would be Most Appreciate
