I’ve been redoing our password expiration reminder script for my company, and due to some convoluted things it needs to do, I decided to invest some time learning some of the Advanced Powershell Function options.

The new script has only a single line outside of functions and using the "process" part of an Advanced Function, I do all the iteration via this, instead of foreach loops.

This ends with a nice single line that pipes the AD users that needs to receive an email, to the function that creates the object used by Send-MailMessage, then pipes that object and splats it to be used in the Send-MailMessage.

Can really encourage anyone writing scripts to take some time utilising this.

A code example of how that looks:

$accountsToSendEmail | New-PreparedMailObject -includeManager | Foreach-Object { Send-MailMessage @_ }
