Adding email address to Active Directory

Question

I am a beginner in PowerShell. I have 1500 service accounts in Active Directory which are missing email addresses; I want to update the SAME email addresses in all the accounts.

Example email address: ecertprocess@abc.com

Please help me writing this PowerShell code.

I have all accounts SamAccountName and DN details.

Answer 1

This will find all the users who don't have a email address (You can change the SearchBase) and add email address of them.

Get-ADUser -Filter * -Properties * -SearchBase "dc=test,dc=net" | Where-Object {$_.EmailAddress -eq ''} | ForEach {Set-ADUser -Identity $_.SamAccountName -EmailAddress "Email Address"}

If you have list of users in a csv like:

SamAccountName,
xxx,
yyy,

then:

Import-Csv "Filepath" -Header SamAccountName -Delimiter "," | ForEach {Set-ADUser -Identity $_.SamAccountName -EmailAddress "Email Address"}
