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

Question

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 protected] -> Office 365 e-mail system
• [email protected] -> Office 365 e-mail system
• [email protected] -> Office 365 e-mail system
• [email protected] -> Office 365 e-mail system -> SAP SMTP server
• [email protected] -> Office 365 e-mail system
• [email protected] -> Office 365 e-mail system

Solution

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.

What do you mean under SAP SMTP server? AFAIK, SAP is bundled with no SMTP mail server and requires external one.

Unfortunately the article only describes how to forward e-mails to another Exchange server, non an SAP SMTP server. From the KB: 'This article describes how to configure a mailbox to forward mail to either a mail-enabled contact (a custom recipient in Exchange Server 5.5) or another mailbox on an Exchange 2000 computer or on an Exchange Server 2003 computer.'

See those lines you just copied pasted? take a closer look at the words "a mail-enabled contact", this is what you need to make this trick work.
