Hello,

I am looking for a Power Shell script to add new SMTP address 200 users and do not want to touch existing SMTP and X.500 addresses. am using Exchange server 2010 sp1

Can someone help ?

i tried with the below script executing on exchange PS, i didnt receive any error and there is no result also.. 

Import-Csv c:\data.csv | Foreach{
$maileg = Get-Mailbox -Identity $_.Name
$maileg.EmailAddresses += $_.emailaddress
}

Hi,

Use this script :

Import-Csv c:\data.csv | Foreach{set-mailbox -identity $_.Alias -EmailAddresses @{add=$_.emailaddress}}

 Make sure  you have  a data.csv file with  at least two header  like below :

Alias,emailaddress

user1,user1@newaddress.com
