Office 365 Smtp Relay Not Working

As in this is only my 3rd week on the job so go easy on me.

Office 365 smtp relay not working.

Microsoft 365 or office 365 smtp relay has higher sending limits than smtp client submission. We have a few devices that need send only email. I have an smtp relay server that is setup and working correctly on a 2008 server. If you re confused about what smtp is click here to jump down to the section where i ve explained it.

The new server has a different internal ip external ip and server. To set up an smtp relay you must first create a connector in office 365 to accept smtp transactions. Log in to your office 365 tenant open the exchange admin center and click mail flow and click connectors. Microsoft 365 or office 365 smtp relay does not require the use of a licensed microsoft 365 or office 365 mailbox to send emails.

After you ve got that background you can come back here to set things up. Use a dedicated relay connector to send emails through the office 365 smtp relay. Our mail system was migrated from a local exchange server to office 365. This connector will receive smtp relay transactions from the application or device.

This can be caused by a number of issues. However when using office 365 you may have to configure an smtp relay on your mail server s end for it work correctly. I set up my printer for microsoft 365 or office 365 smtp relay but it s not sending email or my device was sending email using smtp relay but it stopped working. Before you attempt to create a connector be sure your account has the proper exchange online permissions.

I cannot send outgoing emails with the microsoft office 365 email server. A common reason for issues with microsoft 365 or office 365 smtp relay is a blocked ip address. Follow the below steps to set this up. Senders are not bound by the 30 messages per minute or 10 000 recipients per day limits.

This is my first post as a new sys admin. I configured an imap smtp client with thunderbird working perfectly.
