How to route select e-mails from Office 365 to another SMTP Server

  • 772

I have set up an SAP system to act as an SMTP server on port 25000.

The company uses Office 365 as its email provider.

Is it possible to route/forward e-mails that are delivered to a specific e-mail account from the Office 365 server to the SAP SMTP server?

e.g.

email

    It is not possible to route select e-mails from Office 365 to another SMTP Server, at least not an SAP SMTP server.

    I ended up forwarding e-mails from one domain to another - using the second domain as an 'SAP e-mail only domain', which would be routed to the SAP e-mail server:

    [email protected] -> [email protected] -> SAP SMTP server

    This way, people are able to send e-mails to the company, using the companies proper domain. The e-mails then get routed to another domain (which people don't see) and the e-mail gets received by the SAP system.

  2. Yes you can. MS call in "Conditional mail routing in Exchange Online".

    1. Set up a connector from Office 365 to your email server.
    2. Create a mail flow rule that'll send mail to it based on the criteria you define.

    There is links about that:

  3. Yes, you can.

    To summrize the steps, you need to:

    1. Create a contact inside Exchange.
    2. Mail-Enable the contact you just created.
    3. Enable mail forward from the users to the newly created contact.

    The steps are well documented in this Microsoft Knowledge Base: http://support.microsoft.com/kb/281926

    Note that there might be some step variations, but the idea are essentially the same.
