Powershell: Parameter input e-mail script validation

This is a little trick I used for doing an e-mail check verification in  a powershell script. The reason why I did choose for ValidateScript is that you can customize the error message a bit.

It’s possible to use ValidatePattern with the  same RegEx but, when there is no match you will get a  strange error that your input doesn’t fit with the RegEx used

If ($_ -match "\w+@\w+\.\w+") {
else {
Throw "$_ is not a valid e-mail address "
