New User create in Exchange 2010 does not exist in AD RRS feed

  • Question

  • I have create a user in Exchange 2010 using management console. But when i try to send a mail to that address from same domain it gives delivery failure. Then i checked in AD server and there is no such user create in AD even though user is in Exchange server. We have AD 2008 R2 x64 and exchange 2010 runs on server 2008 R2

  • Not possible.

    Exchange doesn't have its own list of users, it is using the AD to store the user information. Therefore if you can see the user in EMC then the user is in the domain somewhere. If you have multiple domain controlelrs then it could be poor replication which means taht the information is out of sync.

  • I would show the Organizational Unit column in EMC to see where the user account supposedly lives in AD, then check all DCs to see if the user exists on all of the,.

  • make sure entire directory is selected, not specific OU when searching for the user.

  • What delivery failure do you get?

    Could be that the new user isn't on the OAB just yet.

    Send via OWA and see if it works.

  • Its sure shot AD replication issue...

    However once we get the ndr message we can tell what might have caused the mail delivery failure.

    You can try to create a test mailbox and while creating a mailbox specify a domain controller. You should be able to see the user on that domain controller.

  • Hi

      Do you have anything update on your issue ?

      1. Please run Get-Mailbox and check the user.

          Do you create it successfully?

      2. Please check user on other AD ?

          Maybe it is AD replication problem.
