For AD SMTP and Alias’<\/p>\n\n\n\n
<#\n.SYNOPSIS\n Export SMTP addresses (primary + secondary) from AD users.\n\n.DESCRIPTION\n Uses Get-ADUser to collect the 'proxyAddresses' and 'mail' attributes.\n - Primary SMTP is the address with the \"SMTP:\" prefix (uppercase).\n - Other SMTP addresses are those with the \"smtp:\" prefix (lowercase).\n - If proxyAddresses is empty, the script will attempt to use the 'mail' attribute as primary.\n\n.PARAMETER OutputCsv\n File path for exported CSV. Default: .\\AD-SMTP-Addresses.csv\n\n.PARAMETER SearchBase\n Optional AD container (distinguishedName) to restrict the search.\n\n.PARAMETER IncludeDisabled\n If specified, include disabled accounts as well. By default disabled accounts are excluded.\n\n.EXAMPLE\n .\\Export-AD-SMTP.ps1 -OutputCsv C:\\temp\\smtp-addresses.csv\n\n#>\n\nparam(\n [string]$OutputCsv = \".\\AD-SMTP-Addresses.csv\",\n [string]$SearchBase,\n [switch]$IncludeDisabled\n)\n\n# Ensure ActiveDirectory module is available\nif (-not (Get-Module -ListAvailable -Name ActiveDirectory)) {\n Write-Error \"The ActiveDirectory module is not installed or available.
