Hi We need to add additional SMTP addresses for multiple users, based on their A.D. OU - Exchange 2010 SP1 Is there a powershell script way of doing this for multiple users ? I've found a couple of scripts to do this for individual users but not for many. Thanks

Hi, You could use an e-mail address policy - based on OU location. That would also secure that future recipients would get the desired e-mail addresses http://technet.microsoft.com/en-us/library/bb125137.aspx Leif

Hi Thanks for that. It's possible some people will have different addresses from others and I think (correct me if I'm wrong ?) the policy would apply the addresses to ALL users so they would all have the same SMTP addresses ? Thanks

As Leif said, OU Based policy, hence when you apply the policy it will be applied on those users only who are in that OU. Cheers,Gulab | MCITP: Exchange 2010 | MCITP: Exchange 2007 | Skype: Gulab.Mallah | Blog: www.ExchangeRanger.blogspot.com

Hi jarweb, Yes, you can apply the policy based on OU. Select the recipient container where you want to apply the filter If you want to specify a different recipient container, click Browse to open the Select Organizational Unit dialog box. Specify an organizational unit (OU), and then click OK. The recipient container filters the recipients that the e-mail address policy will affect based upon their location in Active Directory.

1. There's a number of filters you can use. When you create a EAP you dont have to always apply to all the users. If users aren't in a particular OU then you can target users based on other attributes such as office, location etc... If you want yu can create your own customer attribute and set this for users and then base your EAP on that so that those specifc users get the additional SMTP. 2. You can also use admodifym this is a handy tool - http://technet.microsoft.com/en-us/library/aa996216(EXCHG.65).aspxSukh

While I agree that you should use a policy based on OU, here is a script which you can easily adapt to your needs if you for some reason still prefer to use PowerShell.
