you can add additional emails with AD for each user. For example, if user is myuser@domain.com, you can add another SMTP address... firstname.myuser@domain.com and both addresses will point to user interchangably. If you change the main email address for user, the only difference you will notice is different email address. You can allways change it back if need be.

Yes!
If you change the Email address of a user in general tab, after the time interval it will again get back to the Recipient Email address and it will become the Primary address and the Email address which you have modified will become Secondary address in the user email address properties.

To check the same please follow this steps.
Create a test user.
Assiciate a mailbox to him.
After creating the mailbox, in Exchange System Manager update the Domain RUS.
You will get the Default Email address.
Change the address in the AD account properties in General tab.
Again go the ESM and try to update the Domain RUS.
You will find the users email address is back to the default one, and the address which you have set will be in the secondary email address.

Please try this and revert back if you have query.

Thanks

The smtp domains which are stamped via RUS would be overwritten.. If you need to specify secondary smtp addresses for some mailboxes, you can do that via email field in general tab of AD, that will not be overwritten by RUS..

Hey guys, for a test purpose I change the email adr directly in Email field in AD...and it doesn't create a secondary stmp but just change the Primary SMTP.


Exemple:

1- I had: user.test1@mydomain.com
2- Change email adr in Mail field from AD for: user.test2@mydomain.com
3- Result: the primary email has changed to: user.test2@mydomain.com

p-s: I went in ESM and chose "Update Now" for both RUS:

- recipient Update Service (MyDomain)
- recipient Update Service (Enterprise configuration)


Is it normal or it will just take a while before RUS will put it back to user.test1@mydomain.com?

Use "Email Addresses" tab under user properties to add smtp address.

Quoted from another...
Exchange's RUS is only as good as the Active Directory information on the domain controller.  While RUS suffers more than most services with latency, to be fair, if the Windows 2003 operating system was constantly checking every attribute of every object in Active Directory, then there would be no time for useful work.

Update Now - Recalculates the Exchange 2003 address list memberships.  By default RUS recalculates every 15 minutes, so pressing the button can save you waiting and wondering if it worked.

Rebuild - Starts from scratch, rechecks any new extension for example, changing CPEXCH.NET --> CPEXCH.com.  Beware that on a production Exchange 2003 server this could take hours.

You force Domain RUS, and check you will find the default one and the newly created will be in the secondary email address list in email address tab.

Check that out!

As I said see my comment: 14/09/10 05:13 AM, ID: 33671479

I force RUS to update now and my primary email adr is the new one that I changed not the origional.

Is that normal for Exchange 2003 SP2? I would like to know what you think guys!

Thank you.
