    Create a mail-enabled Contact and have the AD mailbox object in the AD
    set to forward the mail to the Contact. Or replace the mailbox inyour
    AD with a mail-enabled Contact (or a mail-enabled user if they need
    access to resources in your organization).
     
    Forwarding (vs. redirecting) mail at the Inbox rule level will present
    a problem becasue the mail will appear to come from the mailbox inyour
    organization, not from the original sender.

    Well what we exactly need is to Auto forward around 1000 users emails from our A.domain.com to other company B.domain.com Automatically and also and send auto response to send future emails to new email address.

    can this be achieved ? please give us detailed response

    See my previous answer.

    This is a bad idea. With that many addresses being sent to another
    company, how will you deal with the message sloops that are an
    inevitable consequence of that pratcice?
     
    >can this be achieved ? please give us detailed response
     
    Half of it can. I'd say leave the notification of e-mail address
    changes up to the new company and, after a suitably long period, just
    remove the old addresses from your organization and let the other
    company deal with the problem.

    But how to deal with auto response messages to send to new email system , because old system should notify the user , when you are reaching the new system it is directly landing there how it will recognize that it came from old and you should use new email address.

    I guess auto response is not supported in these scnerios by Microsoft.

    Outlook can use an autoreply rule, but it's a bad thing to do. If you
    start sending an autoreply and the sender has an autoresponder too
    you'll be filling mailboxes pretty rapidly and maybe even clogging you
    SMTP server to the point where you start running out of resources.

    hi salman gilani,

    Why not consider to directly send a response to the sender to tell them send the message to the new mail address rather than using forward.

    For example: if a sender send a message to the old address, you ORG will send a reject message like: the mail address has been changed, you can continue to send mail to the address: user@newdomain.com

    You can use transport rule to achieve this.

    hope can help you

    thanks,
