Step by step configuration of Outgoing Emails from SharePoint to Microsoft Online
First of all your SharePoint server should be added to Microsoft online safe sender list, so that SharePoint server can connect and deliver emails to Microsoft Exchange online.
SharePoint by default is configured to send Email over port 25 (default SMTP) but Microsoft online services are configured to receive Emails over port 587.
In order to bridge the gap between these two things, we can use in built feature of Windows Server OS to route Emails
- We will be sending Emails to SharePoint Server OS itself over port 25.
- Windows server SMTP in turn will route the Emails to Microsoft online over port 587
