    How can I exclude a domain from the Exchange, overriding any Active Directory user SMTP Properties.

    The problem is that the Default domain is using an external Mail Service, and when I use other email accounts from other domains that I have configured in the AD/Exchange to send emails to the default SMTP Domain, I get a reply with this message:

    Remote Server returned '550 5.1.3 STOREDRV.Submit; invalid recipient address.

    Thanks

    Hi PDMFC,

    Thank you for your question.

    As Byron said, we could refer to the following steps:

    1. Create a new accept domain: https://technet.microsoft.com/en-us/library/jj657734(v=exchg.150).aspx
    2. Modify email address policy: https://technet.microsoft.com/en-us/library/bb232171(v=exchg.150).aspx 
    3. Remove the former accept domain: https://technet.microsoft.com/en-us/library/aa998909(v=exchg.160).aspx 

    In addition, please make sure you have record new accept domain in ISP and could be solved on the Internet.

    Best Regard,

    Jim Xu

    You need to edit the Default email address policy to remove the domain from that policy. You may also need to add additional domains that you've added as accepted domains.

    Look at your accepted domains. If Exchange server is not responsible for a domain listed in accepted domains, then remove it.

    However, if you remove it, no one in the Exchange organization can use that SMTP domain.

    If the domain needs to be shared by Exchange and an external email system, then you can configure the accepted domain and an internal relay. In which case, it will try to deliver internally first, then to the external organization.

    AD is not Exchange, Exchange is not AD. Two completely different beasts. 

    Your send connector is forwarding all e-mails to your external Service. 

    Fix it.

    No, that's the oposite. The problem is that Exchange send connector, isn't forwarding emails to the External Service, because that's the default domain.

    The mailboxes for the default domain aren't hosted by Exchange.

    Yes, you can remove the default domain. However, you may need to designate another domain as the default before you remove that one.

    Ok, I've tried remove the Domain, but the It doesn't let me do that, and the error Message is:

    Can't remove the Domain, because he is referenced in a email address policy, by the model of proxy 'SMTP:@<my domain>.com'.

    How can I remove this email address policy, any ideas?

    Thanks
