Routing Mail in Exchange

johncolfer used Ask the Experts™

A situation arose in my company where I had to move an email address from an existing user to a newly created user. Here's what I did:

1. Created a new mailbox and user object
2. Renamed the email address on the existing account
3. Added the email address that was on the old mailbox to the newly created mailbox.
4. Restarted the transport service and waited for over 12 hours.

So at the moment mail from outside exchange goes to the correct mailbox, but mail sent from inside the organistion goes to the old mailbox. Any ideas on how to fix this?

Running MS Exchange 2010 SP3.

Any questions please let me know.

Old emails (replies) from inside the organization use legacyExchangeDN, new emails use cache (nk2 files).
you can move the old user legacyExchangeDN into another x500 of the new user (BUT this will cause all replies to go to the new user not just those related to the specific email address).
Regarding new mails you will need to clear cache on the outlooks of the other clients. (

As stated new emails when selecting the email from the GAL should go directly to the new mailbox. However anything else that was prior to the change needs to have the x500 address confgiured on the new mailbox.

Also make sure that there are no forwarding rules or anything else that might be catching the old emails.

Best way to test this is through OWA to ensure that there is no caching issues.

Glad I could help, thanks for the feedback.
