  • exchange setup with external mail server

    Hi,

    We would like to configure exchange in a certain way, but as i don't have much expirience with it i would like to discuss it with more expirienced people.

    Our organisation has mail server at ISP that serves us well for email and we would like to continue using it. Internaly we are going to start using exchange to store out email and calendars.

    We have a number of mobile workers that acces the email through ISP-s webmail while on the road, so we would like to keep this functionality.
    Our office's link to the internet is currently rather poor quality (in terms of reliability) and we have no public ip addres available.

    This considerations, along with security, made us think that we would like to continue to use our ISP to handle email and use something like POP connector to fetch email internaly and SMTP relay to send it. We would like not to expose our server to connections from the outside (pop, outlook web access), and anyway it would have to be via dynamic dns address.

    We have a question about this kind of setup. Is it possible to see mails sent internaly (through exchange, between recipients in our organisation) on our ISP-s mailbox-es? How could we setup this?

    What you are talking about is sharing the SMTP namespace.
    There are a number of methods of doing this, start with the KB article here:
    http://support.microsoft.com/default.aspx?kbid=321721

    For email delivery, see if the ISP or email hosting company supports ETRN. This is much better than using any POP3 connectors and will give you a similar type of service to true SMTP delivery.

    Do make sure that you are using Exchange for at least internal email - because even if you don't, Outlook will try to. Lots of people try to use it for internal email storage only, which is not what it was designed for. Trying to fight Exchange being used as an email server is a battle you will lose.

      Thanks for the pointer, I'll start reading tommorow.

      I'm not trying to fight exchange, we will use it for internal mail and calendar.
      I would just like to have internal emails available on the outside mail server so users can use it's web acces while on the road...

      Thanx,
      Damir

        If you want access to internal email while on the road, why don't you use it for all email? That is what it is designed for and will provide your users with a single interface for all email.
