Hi, i have tried the code below, which succesfully encrpyt outlook emails and microsoft word, including password into string. but does not work when attempting to unencrpt. I get not responding application and have to close.  grateful for anyones attention to fix code.

You might have better luck with this on a forum like StackOverflow.com. However, even there you will earn frowns (actually, it's demerit points there) if you don't learn how to post your code as code.

I think you're going to have issues doing this. If the data is important enough to encrypt then you should probably hire someone to make a rock-solid setup for you that will encrypt and decrypt the data. Proper encryption isn't just about scrambling some text.

If you want to do it yourself, you might look into this post: https://stackoverflow.com/questions/41932308/encrypt-outlook-mail-programmatically-via-vba
