So this comes up a lot. You have a field in AD but your script will not modify it. You need to change the field attribute to the new entry but the logical commands (like -delete or $Null) don’t work and just return errors.

These special fields require a combo command request which combines get-aduser with set-aduser. Then you simply enter a -clear command and you’re all done.

I don’t know why this is such a hard thing to find a solution for on the internet. Most of the sites I visited had overcomplicated lines of code for this simple command.

Here is the entire command in use to clear the email field in AD.

get-aduser samname | set-aduser -clear mail

The “samname” is the account logon name.

Here is a pretty decent list of all the field names:
