Distribute Emails via Office 365 / Microsoft Graph with List & Label
Microsoft is putting more and more obstacles in its Office 365 package, making it difficult to send SMTP emails “just like that” with basic authentication (see e.g. here) and with MAPI/XMAPI in the cloud anyway. But on-premise also brings new challenges (have you ever dealt with our Cross-Bitness-Proxy for x86 applications and x64 Office? 🙂 ). So it was about time to offer a new, up-to-date solution for the very frequently used email delivery.
