SharePoint Online Incoming E-Mail Settings

Marius Smith - we have a cool app developed to get the Incoming Email experience in SharePoint Online libraries and OneDrive for Business. The app name is "https://appsource.microsoft.com/en-us/product/office/WA200001647?tab=Overview". You can get this app either from the Microsoft App Source or directly from your SharePoint Online site using SharePoint Store. This gives you the same experience as the on-prem Incoming email functionality. In fact, much more than that. You can try this tool for Free for 30-days.

Let me know if any question.

Thanks,

Ashish
