在VB.NET或C＃中添加Exchange电子邮件别名

Question

Using .NET (VB or C#), how can I add an e-mail alias to a user in Active Directory?

I have written code to change the format of our usernames from "first_last" to "first.last.country" and I need to update the e-mail addresses as well. Our solution is to add an alias e-mail to the users in exchange, but I don't know how I can do this using .NET.

Answer 1

This question is quite old but, you never know who may need this info.

The modern way to handle Exchange Server and Active Directory issues at this level is not using vb or c# , sure you can, but the practical and fast) way to do it is using 'powershell' .

On your exchange server use Powershell ISE ; it isvery close to a programming language. There are multiple samples elsewhere of aliases handling.

Here you have the basics: You start loading your environment, your location and version may vary:

. 'C:\Program Files\Microsoft\Exchange Server\V14\bin\RemoteExchange.ps1' 
Import-Module ActiveDirectory

Apply your own logic to get the user you want to modify and the alias:

$mb = get-Mailbox .....
$mb | Set-Mailbox -EmailAddressPolicyEnabled $false
$alias = "newalias@domain"
if(-not($mb.EmailAddresses -ccontains $alias)){
  $mb | Set-Mailbox -EmailAddresses @{Add="$alias" }
}
