Update Active Directory "mail" attribute via PowerShell - powershell

Question

I'm trying to update the email address listed in AD for all the users in a particular OU. This is the powershell script I'm using, but it's not working properly
Import-Module ActiveDirectory
Get-ADUser -Filter * -SearchBase "OU=OtherOU,OU=SomeOu,DC=Domain,DC=local" | Set-ADUser -email $_.samaccountname#domain.com
I think it's because $_.samaccountname isn't returning anything when I try to do Set-ADUser.
Can anyone point me in the right direction for fixing this? Thanks!

Answer 1

Create a csv file with SamAccountName & email address
"SamAccountName","EmailAddress"
"john","john#xyz.com"
step 1: import to a variable
$users = Import-Csv .\email.csv
step 2: Call the variable
foreach ($user in $users) {
Set-ADUser -Identity $user.SamAccountName -EmailAddress $user.EmailAddress
}

Answer 2

In the current context $_ is null. You need to use Foreach-Object in order for $_ to be available.
Get-ADUser -Filter * ... | Foreach-Object{
Set-ADUser -Identity $_ -Email "$($_.samaccountname)#domain.com"
}

Answer 3

I suspect you'll need to use a subexpression for that:
"$($_.samaccountname)#domain.com"

Answer 4

Assuming username is domain\user1 or user1#domain.com
$user = "user1"
Set-ADUser $user -emailaddress "firtname.lastname#xyz.com"
Get-ADUser -Identity $user -Properties emailaddress

Answer 5

Get-ADUser -Filter * -SearchScope Subtree -SearchBase "OU=OUName,DC=domain,DC=com" |
Foreach-Object { Set-ADUser -Identity $_ -Email "$($_.samaccountname)#domain.com" }
