Excellent article !
May be you can answer my question about our RUS problem:
Our organization started to migrate from Exchange 5.5 to Exchange 2003.
We have one Exchange organization with nine Exchange 5.5 sites (9 servers) and we plan to consolidate them to into 5 routing groups (5 servers) of exchange 2003 . We have an AD domain in native mode (Win2k DC), and Exchange 2003 SP1 is installed on our Windows 2003 servers. We have more than 900 user mailboxes.
In most of the cases our user SMTP addresses are defined in the format: <firstname><first_letter_of_surname>@domain.com
The name of an AD User account never equals <firstname><first_letter_of_surname>, and each of our users has only one SMTP address.
In our Exchange 2003 organization the Default recipient policy (with Lowest priority) is and 9 recipients policies from Exchange 5.5 sites (with Highest priority). All the policies are defined to have only one SMTP address.
The problem is:
When the RUS is running (event id 8329), those users with a discrepancy between their AD account name and first part of their SMTP address are automatically given a second SMTP address (as their primary SMTP address) in the format <user_AD_account>@domain.com. Those users whose SMTP address is already in the format <user_AD_account>@domain.com are not given any additional SMTP address.
This same thing happens also with user X400 addresses and with Distribution Lists X400/SMTP addresses.
We would like to know if the above is normal behavior and if any workaround available.
Currently we have disabled RUS from running.
Thanks
