Setup RN Alerts to send message to O365 account

[Buildster]

Hi guys,

I'm trying to setup ReadyNAS alerts to be sent from mailbox1@domain1.com to mailbox2@domain2.com.

However, I'm getting this error: "Cannot send a test message. From address is not accepted by the server. Check From address settings.

Both mailboxes are hosted in Exchange Online. 

Could you please advise what is wrong.

Thanks

You need to be using an SMTP server on the NAS.  Are you using the settings here?
