Hi All, in this post I am going to share information on how can you update an attribute(s) in AD for multiple objects. In this post, I am using a CSV file that contains users’ First Name, Last Name, their login name and Employee ID. I wanted to update Employee ID for all the users listed in CSV file. To achieve this, I have complied a PowerShell script that uses CSV file and update AD attributes for multiple users. CSV file: I saved CSV file in C:\ADTest.CSV . I ran following PowerShell script as admin. This script import CSV data, updates EmployeeID data for each login name (sAMAccountName) listed in CSV file. #Import Active Directory module Import-Module ActiveDirectory #Import CSV file $Obj = Import-Csv "C:\ADTest.csv" foreach ( $Usr in $Obj ) { Get-ADUser -Filter "sAMAccountName -eq ' $( $u . sAMAccountName) '" -properties * | set-aduser -replace @{employeeID = " $( $u . employeeID) " } -
