Q

Getting mail to new users

I have just made a couple of domain changes. I've created a child domain and changed from a 2000 native mode to windows 2003 domain. All of the DC's are 2003 standard. After making these changes, I ran domainprep on the child domain (successfully) and then added RUS to the only Exchange server (2003 Enterprise) I have. The Exchange server is in the parent domain, and the RUS connects to the child domain. When I create a new user with a mailbox, the user can: Create and send email internally and externally as well as receive email internally. My problem is this: The new user cannot receive email from any external source. What am I missing? Where do I look?

I have just made a couple of domain changes.

  1. Created a child domain.
  2. Changed from a 2000 native mode to windows 2003 domain.

All of the DC's are 2003 standard.

After making these changes, I ran domainprep on the child domain (successfully) and then added RUS to the only exchange server (2003 Enterprise) I have. The Exchange server is in the parent domain, and the RUS connects to the child domain.

When I create a new user with a mailbox, the user can:

  1. Create and send email internally and externally.
  2. Receive email internally.

My problem is this: The new user cannot receive email from any external source.

What am I missing? Where do I look?

Since these users can send and receive mail internally, a Recipient Policy is getting applied to these users. One possibility is if you have multiple Recipient Policies and the one with a valid/registered SMTP domain filters out these new users, so they never get a valid SMTP email address from the registered domain(s). I would check the email addresses for these new users -- if they got the correct Recipient Policy applied, they would have the correct email addresses from a Recipient Policy that generates a valid email address from a registered domain.

If that's not the case, check your Recipient Polices -- are you applying the correct filter that picks up these users from the child domain? If not, you would have to modify the filter so it picks these up.
