Based on the defined e-mail addresses, every affected object gets this E-Mail address.
The Default installation creates two default policies: It is not possible to deactivate the default X400 address type because it is possible that some old components like custom applications etc. It is possible to create the following proxy addresses: When you create a new address type or modify an existing one every new and existing object gets the new address type or address changes.
In exchange 2003, I updated the default recipient policy to include 2 new e-mail domains, applied the policy, did 'update now' in recipient update service.
I am able to send mails and receive to all addresses (all suffixes).
Make sure all your user details are correct as that is what we’ll use to generate the proxy addresses.
