Hello All,

 

This is my first Technical Article. Please read and let me know if there are any modifications are needed.

As correctly pointed out by Suhel,

This blog post is about option 1) Authenticate your device or application directly with a Microsoft 365 or Office 365 mailbox, and send mail using SMTP AUTH client submission

Kindly Refer-

You all might have seen the same content, topic by somebody or somewhere in the blogs.sap.com but one thing which was bothering me is nobody kept it simple and in one place. No worries, Here I’m. I was struggling but I don’t want anybody else to struggle.

 

This Blog is about SMTP- Technical Architecture with Office 365 (and SAP S/4 HANA system is hosted in Private Cloud). Point to remember, Inbound as well as outbound with Important Points. Let’s start!

 

Login to your SAP S/4 HANA System, consider you have 3-tier landscape then you can run a PoC in Development Landscape or directly in your Test Landscape. Upto you. Remember: None of the settings is transportable.

 

For Outbound SMTP Configuration


In your Development System, Run Transaction Code *SCOT*, you will see something as below,


SCOT


 

Select and click Create Node using the Wizard (easy).


Create Node


I have entered SMTP_D (for Development Landscape), further on you can have SMTP_Q for Quality Landscape, SMTP_T for Test Landscape and finally SMTP_P for Production landscape (your selection). Click Continue.

 

Enter Mail Host is, smtp.office365.com and Mail Port as 587 (Standard but if there are any changes in it then Microsoft Office 365 Team can help you; ask them about the Host and Port).

 

IMPORTANT


Before you continue, ensure that you must have a mailbox information with you. You need to have a mailbox (e.g., noreply@yourdomain.com) so that you can complete the SCOT related configuration.


Also, please allow/ whitelist smtp.office365.com with port 587 in your firewall. If SAP S/4 HANA system is hosted in Private Cloud under RISE with SAP offering, then raise an SR to get it whitelisted/ Allowed from.



Create Node- Continue


Click Setting. This is important Step unless setup is tweaked by your organizations Microsoft Office 365 Team.

 

Enter noreply@yourdomain.com as UserName, and Password for that account. Microsoft Office 365 Team must provide you the Password of the newly created mailbox.


Security Setting for Node


Click Ok

By default, it is on 'No', but click 'Yes' in security warning.


Click Continue. Then Select Internet, click Continue


Continue



Continue


Add ‘*’ in Address area and click Continue. You can restrict the Address Area too.


Continue



Continue



Continue


Select N, Click Continue.


Continue


Anything which could be ok here, we have used 0 hrs and 1 minutes


Continue


As a final Step, this is how it will look.


Final SCOT Screen


Click Settings


Outbound Settings


Add default Domain as yourdomain.com (your Organizations Domain, For example, SAP as an Organization the domain would be SAP.com)


Your Domain as Default Domain


Click Save.

 

Now, Schedule Job to send the mails, Click Send Jobs.


Schedule Background/ Batch Jobs to Send the mails


Click New, and select Schedule Job for all Address Types,


Background Job- New to send mails



Continue



Save it


Test the e-Mail Send Functionality.  Select SMTP Nodes, go to Utilities, and click Send Test Mail.


Test e-Mail sending



Enter Recipient


Run SOST to see the status of sent e-mail,


Transaction Code: SOST


Blue colored status with msg code as 718 means All is Ok with your SMTP Setup.


Successful Sent


Final Check


Verify the recipients mail box


 

How it looks,


Technical Architecture


 

-: Important :-


Every User ID must have noreply@yourdomain.com  as an e-Mail ID in communication tab (transaction code SU01d) to send the e-Mails to anyone. SAP Security Team can maintain the same using SU01 Transaction Code.


 

Once you are done with all the above Steps then you will be able to send the e-Mails from SAP S/4 HANA system to III party e-Mail ID's and your corporate e-Mail ID's. Ensure, in SOST, Status must be Blue and Message Code must be 718.

 

Top 3 reasons which will cause a disruption in sending e-Mails from SAP System.

  1. SMTP Auth (basically, the User ID and Password to get authenticated on Office 365) is having any problem.

  2. SAP S/4 HANA system is not able to reach to smtp.office365.com on port 587 (it is blocked on Firewall or not whitelisted in Rules)

  3. An User who is trying to send the mail doesn't have the noreply@yourdomain.com as an e-Mail ID in Communication Tab.


 

To Troubleshoot the Issue, Best way is,

  1. Run SMICM and go to ICM Logs.

  2. Increase the Trace Level to 3.

  3. Try sending e-Mail from SAP S/4 HANA system and check the trace.

Hope this will help you setup e-Mail with Office 365 in SAP S/4 HANA system (in Private Cloud). Do let me know if I missed any points or if you have any questions. Happy to answer.

 

Thank you for reading.
