Mailbox Usage

This code sample retrieves the following parameters of an Exchange mailbox:

Mailbox size

In the below code sample, the $mailboxParams variable represents properties of an Exchange mailbox. To retrieve the properties, use the IAdmExchangeMailParametersOps::GetMailParameters method.

How

[Reflection.Assembly]::LoadWithPartialName("Softerra.Adaxes.Adsi")

# Connect to the Adaxes service
$ns = New-Object "Softerra.Adaxes.Adsi.AdmNamespace"
$service = $ns.GetServiceDirectly("localhost")

# Bind to the user
$userDN = "CN=John Smith,CN=Users,DC=domain,DC=com"
$user = $service.OpenObject("Adaxes://$userDN", $null, $null, 0)

# Get Exchange properties
$mailboxParams = $user.GetMailParameters()

# The $mailboxParams variable represents properties of an Exchange mailbox

# Mailbox size

# Storage quotas

    {
