Find SMTP addresses using ActiveDirectory module in PowerShell

# On a DC, in Powershell:
#See all smtp addresses for specific AD User
Get-ADObject -Properties proxyAddresses -Filter {samaccountname -eq "ADUserSamAccountName"} | select -ExpandProperty proxyaddresses

#See all smtp addresses by searching for parts of an smtp address
Get-ADObject -Properties mail, proxyAddresses -Filter {mail -like "*portionOfMailAddress*"} | select -ExpandProperty proxyaddresses


# If you have RSAT ( which you should ) on your own PC:
#get the credetial of an administrative user
$cred = Get-Credential DOMAIN\User

# Import the Active Directory Module
Import-Module ActiveDirectory

#See all smtp addresses for specific AD User
Get-ADObject -Credential $cred -Properties proxyAddresses -Filter {samaccountname -eq "ADUserSamAccountName"} | select -ExpandProperty proxyaddresses

#See all smtp addresses by searching for parts of an smtp address
