Summary: Use the Active Directory Module to get the information from the “Notes” field.
I’m trying to find the Active Directory property to use to access the Notes field when I’m viewing a user or a group. Could you lend me a hand?
No problem at all. The property you are looking for is info and can be added when you use Get-ADuser or Get-ADGroup. I like to add description as well to pull in most of the descriptive details. Here is an example:
Get-ADUser -filter * -properties info,description
Get-ADGroup -filter * properties info,description

Is this the case with multiple version of powershell?
From within Powershell_ISE:I am seeing on one host in one domain that the INFO field appears, yet same command on the second host (second domain, different account), the fields are not present even after adding INFO to the properties.
