Powershell script to loop through MSOLUsers in CSV file until they are synced to Azure AD/Entra ID

Question

Hi all,

I have an input CSV file like this:

UserPrincipalName

******@test.com

******@test.com

These users are located in our On Premise Active Directory but are NOT synced to our Azure AD/Entra ID (they are in an OU which we exclude from syncing to Azure AD/Entra ID).

Occasionally, we need to be able to sync these users to Azure AD/Entra ID. We do this by simply moving the users out of the "Do Not Sync" OU. I would like to have a PowerShell script so that when it is run, it will check to see when the users have been synced to Azure AD/Entra ID. The script requirements would be:

1. Read the contents of the CSV file.
2. Create a loop so that the script will check if the users have synced to Azure AD/Entra ID.
3. Once all users in the CSV file have been confirmed that they have been synced to Azure AD/Entra ID, exit the loop.

What I have right now, is a foreach iteration which will read in my input file and check if the MSOLusers exist or not in Azure AD/Entra ID:

$SyncedUsers = Import-Csv D:\Users.csv | Select UserPrincipalName

foreach ($User in $SyncedUsers){

Get-MsolUser -UserPrincipalName $User.UserPrincipalName

}

The above will return an error if the users are not in Azure AD/Entra ID, and will return the MSOLuser if they are in Azure AD/Entra ID. I think I need a "wrapper" loop to check on the status of the Get-MsolUser -UserPrincipalName $User.UserPrincipalName command and to keep looping until all users in the CSV file are synced to Azure AD/Entra ID, but don't know how to incorporate the while loop part!

Thanks in advance!

Hi mark terry,

Please understand that the tag “Microsoft Exchange Online Management” is for general questions related to Exchange Online. For your question about the script which is not supported in our community.

But based on my personal experience, you could try the following script :

$syncedUsers = Import-Csv D:\Users.csv | Select UserPrincipalName
$allUsersSynced = $false
$retryInterval = 60 # seconds to wait before the next retry
while (-not $allUsersSynced) {
    $allUsersSynced = $true # Assume all users are synced, and prove otherwise if a user isn't found
    foreach ($user in $syncedUsers) {
        try {
            Get-MsolUser -UserPrincipalName $user.UserPrincipalName -ErrorAction Stop
            Write-Host "User $($user.UserPrincipalName) is synced."
        }
        catch {
            # If an error is caught, it means the user is not synced yet.
            Write-Host "User $($user.UserPrincipalName) is not synced yet."
            $allUsersSynced = $false
        }
    }
    
    if (-not $allUsersSynced) {
        # Wait for some time before rechecking
        Write-Host "Waiting for $retryInterval seconds before rechecking..."
        Start-Sleep -Seconds $retryInterval
    }
}
Write-Host "All users are now synced."
