[转载代码] [PowerShell每日技巧]从AD中找出没有邮件地址的用户(20131112)

DAIC

LDAP queries are extremely powerful and can help find accounts that are missing information.

This code would return all Active Directory users that actually have a mail address:

$searcher = [ADSISearcher]"(&(sAMAccountType=$(0x30000000))(mail=*))"
$searcher.FindAll() |
  ForEach-Object { $_.GetDirectoryEntry() } |
  Select-Object -Property sAMAccountName, name, mailCOPY

If you want the opposite, negate the query using "!". This would return all Active Directory user accounts that currently have no mail address:

$searcher = [ADSISearcher]"(&(sAMAccountType=$(0x30000000))(!(mail=*)))"
$searcher.FindAll() |
  ForEach-Object { $_.GetDirectoryEntry() } |
  Select-Object -Property sAMAccountName, name, mailCOPY
