Well it sounds like your SMTP server is rejecting your messages. There's not much we can do for you. You'll need to use a different one or maybe you can change your settings to get around it.

@zeroSteiner is correct, that is an SMTP server side issue. You will need to setup your own SMTP server, or find another service. Also I would recommending adjusting the number of emails you are sending out per minute. This can be found in edit > preferances. SMTP Tab

Office365 has throttling limits built in.. No more then 30 messages per minute and no more then 10,000 recipients per day. In addition if they mark you as spam or phishing they will probably stop the access too. This is normal behavior for companies that provide SMTP access to send emails.

We just setting send Rate limit is 1 only. Event if i use email in domain or email of outlook.com . We has permission send same 5 mail only. I has change to gmail, every things ok. If you know where configure this information, please help me. We use office365

See the max_messages_per_connection setting. It's not exposed through the UI, so you'll have to edit the file directly. See the documentation for more details.
