Adding Aliases to AD with PowerShell

Adding aliases in AD is a VERY simple task.

You can just find the user via the ADUC (Active Directory Users and Computers), go to the ‘ attributes’ tab on them, find ‘ proxyaddresses’ and add a new record prefixed with smtp:. For example, you could add ‘ smtp:firstname.lastname@domain.com ‘

But what if you need to add lots of aliases to lots of people?

You can do this with just a CSV file and the right PowerShell commands.
