CHANGING PROXY ADDRESS FOR LOCAL AD USERS

If your Exchange users have problem with Active Sync’s Autodiscover configuration or you’re intending to configure a Hybrid configuration with Microsoft office 365 Exchange Online or Your Lync/Skype for business users are having troubles signing in right after you enable users from the Lync/SfB Panel then this article is for you.

Note: For Lync you’d want to change Account (UPN) Instead of the Proxy Address Attribute for users. For each scenario it might be a different case.

Assuming that I have the following domain list, and I want to add them to my AD user’s proxy address attribute so they can use it as SMTP address

%’sAMAccountName’%@Domain1.com

%’sAMAccountName’%@Domain2.com

%’sAMAccountName’%@Domain3.com

%’sAMAccountName’%@Domain4.com

%’sAMAccountName’%@Domain5.com

%’sAMAccountName’%@cardtekcloud.onmicrosoft.com

First to add main SMTP address we’ll use the attribute %’sAMAccountName’%@Domain.com

Next to add alternative Proxy addresses we’ll use

%’sAMAccountName’%@domain.com

I’ll open ADModify.net app and select the organization that I would like to apply the changes for

I’ll select Domain from the domain list. Then choose the Domain controller and choose only to show users

Click on the green Next button then click Add to List then click Next under the user to continue

I’ll navigate to Email addresses tab to do the changes and place the domain that I would like to use.

I’ll enter whatever domain and use sAMAccountName since it matches the user’s Email address .

IMPORTANT NOTE:

It’s very important to notice that if you’d like to change the domain in the Proxy Address . You ‘ll need to choose an attribute that matches the user’s existing Proxy address username ..

To add the other domains e.g. domain2, domain3 ..etc I’ll follow the exam same steps just change the end @domain2.com.

That should be all. If you have any questions please don’t hesitate to contact me or comment.
