AzureAD/O365 – Update User’s Manager using PowerShell

by

Organizational hierarchy is vital to run everyday activities smoothly in any enterprise. With Azure AD, user’s manager information can be updated easily and this information can be used in other features like Teams and apps that require workflow.

In this post, I’ll go over steps on how to update manager information for a specific user, for a list of users based on information from a csv file and to determine users’ manager information

Make sure you are connected to Azure AD,

$credential = Get-Credential
Connect-AzureAD -credential $credential

To update manager information for a specific user:

$user = Read-Host "Enter user's email address to update Manager information"
$Manager = Read-Host "Enter Manager's email address"
Set-AzureADUserManager -ObjectId (Get-AzureADUser -SearchString $User).Objectid -RefObjectId (Get-AzureADUser -SearchString $Manager).Objectid

To bulk update users’ manager information from a CSV file:

Note: csv file has UserEmail,ManagerEmail as column headers

$list = Import-csv "C:\tmp\SetManager\UsersManagers.csv"
Foreach($entry in $list) {
        $User = $entry.UserEmail
        $Manager = $entry.ManagerEmail
        $UserObj = Get-AzureADUser -SearchString $User
        $ManagerObj = Get-AzureADUser -SearchString $Manager

        Write-Host Updating $UserObj.DisplayName with $ManagerObj.DisplayName as manager -ForegroundColor Yellow

        Set-AzureADUserManager -ObjectId $UserObj.Objectid -RefObjectId $ManagerObj.Objectid

        Write-Host "Update Complete." -ForegroundColor Green

}

To determine a user’s manager:

$user = Read-Host "Enter user's email address to determine Manager information"
(Get-AzureADUserManager -ObjectId (Get-AzureADUser -SearchString $User).Objectid).DisplayName

To determine all users’ manager information in the Azure AD tenant:

$Users = Get-AzureADUser -All $true

ForEach($User in $Users) {

    $Manager = Get-AzureADUserManager -ObjectId $User.Objectid
    If ($Manager) {
    Write-Host $User.DisplayName manager is $Manager.DisplayName -ForegroundColor Green}
    Else {
    Write-Host "No Manager information found" for $User.DisplayName -ForegroundColor Red}
}

Thank you for stopping by. ✌
