    Well, then there's your problem. The O/R address in a message is the
    one assigned to the sender in the other e-mail organization. When you
    reply to that message the O/R address doesn't match any
    legacyExchangeDN value in your AD.
     
    When you reply to a message like that, pick the recipient from your
    GAL (not from the Contacts folder in the mailbox). That should deliver
    the message.

    That error isn't coming from Exchange. Exchange is just reporting the
    problem. It looks like it might be from whatever you're using as a
    smart host (mail.externaluserserver.com).

    Then the two addresses aren't the same.

  • Hi,

    Do you have linux firewall or other configured?

    I found a useful thread, you can check to see if your ISP allow to relay.

  • Hi

    Was that part of a migration?

    Do you have that problem by answering to existing emails or also when you write new emails?
    Did you try to clear the autocomplete cache in Outlook?

    Regards

  • Hi

    No this was a clean install and we migrated emails via PST export/import. I need to check the second one. We created new profiles for all users so hopefully outlook had a clean cache to start with.

    Separately, if I send an email to an external person then I get the below message;

    Delivery has failed to these recipients or groups:

    user@externaldomain.com (user@externaldomain.com)

    A problem occurred during the delivery of this message to this e-mail address. Try sending this message again. If the problem continues, please contact your helpdesk.

    The following organisation rejected your message: mail.externaluserserver.com.

    Diagnostic information for administrators:

    Generating server: MYSERVER.MYDOMAIN.local

    user@externaldomain.com
    mail.externaluserserver.com #553 sorry, that domain isn't in my list of allowed rcpthosts; no valid cert for gatewaying (#5.7.1) ##

    If however I reply to that user's email then it goes out fine.

    Thanks

    Regards

  • Do you use your Exchange Server to send/receive emails, or is there a POP/Imap Server between?

  • Hi

    Exchange is used for sending/receiving emails except POPBeamer is used in place of pop connector to download emails from external POP server.
