eMail Address Policy Root/Child Domain RRS feed

  • Question

  • We have a root/child domain setup and an internal/external domain setup.

    I really need some help because I cannot find the answer. 

    Is there any reason why I need to have email address policies for my sub domains? 

    Please any help is most appreciated.

  • Hi TIA,

    Thanks for your update and clarification.

    That depends on whether you  need @subdomain.com for your users located in the subdomain. Exchange server supports multiple smtp email address and multiple email address policies.

  • Hi,

    E-mail address policies generate the primary and secondary e-mail addresses for your recipients (which include users, contacts, and groups) so they can receive and send e-mail. By default, Microsoft Exchange contains an e-mail address policy that specifies the recipient's alias as the local part of the e-mail address and uses the default accepted domain.

    In another word, without a email address policy, recipients in the Exchange organization will have no email address to send/receive email message.

  • Thank you for your response.   I should have been more specific. 

    I do understand the purpose of the eMail Address policy. 

    With an internal/external domain setup we have a split DNS environment. All users PrimarySMTPAddress must be stamped with our @externalDomain.com.  Exchange does not own the SMTP Domain name space for @externalDomain.com; I share the SMTP Domain name space with Unix Sendmail.

    I have an eMail policy for users to be stamped with @externalDomain.com but I am not sure if I need email address policies which stamp both the @externalDomain.com  and  the secondary proxy address of @subdomain.com. 

    So my question is with the above setup would I need to use secondary proxy addresses for my windows sub domains if I have eMail Address policies which cover my @externalDomain.com?

    TIA

  • Thank you again, I saw this KB article and the examples in the article do not apply.

    Somewhere I read about using subdomains.com for Exchange ActiveSync Policies but I cannot find the article.

    So, would I need to use subdomains.com proxy addresses for Exchange ActiveSync policies?  Last piece to this questions

  • Not sure what do you mean with the Exchange ActiveSync policy. Are you trying to add multiple ActiveSync policies to one user? That shouuld not work because we can add a user to only one Exchange ActiveSync mailbox policy at a time. But a lab testing would be a better way to emulate the environment and unexpected issues.
