powershell - Adding and removing extensionattribute to AD object

Question

I'm using powershell to modify some AD extensionattribute.

This is my code to add an extensionattribute

Set-ADUser -Identity "anyUser" -Add @{extensionAttribute4="myString"}

It works, but how can I remove the same extensionattribute? I can't find anything similar to -remove.

Answer 1

You could try using the -Clear parameter

Example:-Clear Attribute1LDAPDisplayName, Attribute2LDAPDisplayName
