Thank you for asking this question on the Microsoft Q&A Platform.

The following documentation shows you different options to send emails from Exchange online

1. Option 1: Authenticate your device or application directly with a Microsoft 365 or Office 365 mailbox, and send mail using SMTP AUTH client submission
2. Option 2: Send mail directly from your printer or application to Microsoft 365 or Office 365 (direct send)
3. Option 3: Configure a connector to send mail using Microsoft 365 or Office 365 SMTP relay

Here's a comparison of each configuration option and the features they support.

Hope this helps!
