VIM inbound e-mail w.o. (SCOT) SMTP - Pull from EXO ?

[snuden]

Hi all,

In our organization we use Exchange Online for e-mails and I am looking for a secure way to ingest e-mails w. attached invoices into VIM, preferably without using the in-built SAP SMTP end-point.

A couple of considerations:
a) Installing Exchange server on-premise to bridge EXO to On-premise is not an option.

b) Opening network to expose SAP SMTP port to public internet is not an option.

c) A scripted 'pull', retrieving e-mails from Exchange Online, could be an option.

Are there other options?

Relative to Option.c what are the implementation options? Are SAP standard modules available to retrieve and ingest e-mails w. attachments into VIM workflow?

Looking forward to feedback & happy to elaborate further

/Marc

After some time a solution on inbound e-mail reception was identified - this is aligned with Option.c, not exposing SMTP to the public internet.

The solution is to leverage CPI for integration and forwarding of e-mails to SCOT SMTP endpoint. Connectivity w OAuth2 authentication is described in this article: Cloud Integration – Connect to Microsoft 365 Mail with OAuth2 | SAP Blogs

Another option that some customers implement that have less effort is to deploy a webserver such as Microsoft IIS (Internet Information Services) in the same datacenter where SAP is hosted.

Then, expose only the webservice to the public internet with a public IP and configure the network to allow only inbound traffic from the Office365 IP ranges and configure the webserver to route all incoming SMTP messages from O365 to the SMTP service in the SAP servers.

For this to work, the O365 administrator needs to configure something called "Connector" that routes all incoming emails from the mailbox to the public IP of the webserver.
