Why Use Microsoft 365 Email? 

By default, all emails sent via 1stream are sent using our third party mail queueing system, which can cause delays or outages that you would otherwise not see using your own mail server. Especially when it comes to newer email addresses, it's easy to end up on our suppression list and your own mail server avoids that issue entirely.

This will replace the email capability for the PIN Verification Tool and Signal's Voicemail Monitoring.
