Get a user's email address from the username via PowerShell and WMI?
Solution 1
The simplest way is to useActive-Directory.
As you are using PowerShell tag and not PowerShell V2.0 you can use ADSI.
Clear-Host
$dn = New-Object System.DirectoryServices.DirectoryEntry ("LDAP://WM2008R2ENT:389/dc=dom,dc=fr","[email protected]","Pwd")
# Look for a user
$user2Find = "user1"
$Rech = new-object System.DirectoryServices.DirectorySearcher($dn)
$rc = $Rech.filter = "((sAMAccountName=$user2Find))"
$rc = $Rech.SearchScope = "subtree"
$rc = $Rech.PropertiesToLoad.Add("mail");
$theUser = $Rech.FindOne()
if ($theUser -ne $null)
{
Write-Host $theUser.Properties["mail"]
}
You can also use userPrincipalName
instead of sAMAccountName
in the filter, for userPrincipalName
you can use user@domain form.
Using WMI : If you absolutly want to do it with WMI.
$user2Find = "user1"
$query = "SELECT * FROM ds_user where ds_sAMAccountName='$user2find'"
$user = Get-WmiObject -Query $query -Namespace "root\Directory\LDAP"
$user.DS_mail
You can use the second solution localy on your server or from a computer inside the domain, but it's a bit more complicated to authenticate to WMI from outside the domain.
Using PowerShell 2.0
Import-Module activedirectory
$user2Find = "user1"
$user = Get-ADUser $user2Find -Properties mail
$user.mail
Solution 2
Here's another possible way (original source):
PS> [adsisearcher].FullName
System.DirectoryServices.DirectorySearcher
PS> $searcher = [adsisearcher]"(objectClass=user)"
PS> $searcher
CacheResults : True
ClientTimeout : -00:00:01
PropertyNamesOnly : False
Filter : (objectClass=user)
PageSize : 0
PropertiesToLoad : {}
ReferralChasing : External
SearchScope : Subtree
ServerPageTimeLimit : -00:00:01
ServerTimeLimit : -00:00:01
SizeLimit : 0
SearchRoot :
Sort : System.DirectoryServices.SortOption
Asynchronous : False
Tombstone : False
AttributeScopeQuery :
DerefAlias : Never
SecurityMasks : None
ExtendedDN : None
DirectorySynchronization :
VirtualListView :
Site :
Container :
PS> $searcher = [adsisearcher]"(samaccountname=$env:USERNAME)"
PS> $searcher.FindOne().Properties.mail

I have a user's network login name. From PowerShell and WMI is it possible to get a valid email for that user? Note that the login name is different than the name in the email, so I can't just combine the login name with the email domain.
