getting a “Cannot bind argument to parameter ‘Identity’ because it is null” in this script :

# Import Exchange Online PowerShell Module
Import-Module ExchangeOnlineManagement

# Connect to Exchange Online
Connect-ExchangeOnline

# Path to the CSV file
$csvFilePath = "mypathblabla"

# Import the CSV file
$userList = Import-Csv -Path $csvFilePath

# Loop through each user in the CSV file and update the City and Country attributes
foreach ($user in $userList) {
    $email = $user.Email
    $city = $user.City
    $country = $user.Country

    # Update the user attributes
    try {
        Set-Mailbox -Identity $email -City $city -CountryOrRegion $country
        Write-Host "Successfully updated $email with City: $city and Country: $country"
    } catch {
        Write-Host "Failed to update $email. Error: $_"
    }
}

I gathered it to basically put 2 different attributes in the fields “city” and “country” on a loooong list of users 365 mails contained in a csv file.
Could someone explain to me what I am missing here ? (CSV is in the good format : Email,City,Country).

Thank you very much in advance

• Correct CSV
• Search the error
• Thought i should learn powershell extensively for this extensive type of uses ?
