Office 365 Smtp Relay Not Working

Microsoft 365 or office 365 smtp relay has higher sending limits than smtp client submission.

Office 365 smtp relay not working.

This can be caused by a number of issues. Microsoft 365 or office 365 smtp relay does not require the use of a licensed microsoft 365 or office 365 mailbox to send emails. I cannot send outgoing emails with the microsoft office 365 email server. A new 2016 server was created at the same site and smtp was setup using the exact same settings as the 2008 server but it is not working.

Follow the below steps to set this up. We have a few devices that need send only email. However when using office 365 you may have to configure an smtp relay on your mail server s end for it work correctly. The new server has a different internal ip external ip and server.

As in this is only my 3rd week on the job so go easy on me. Log in to your office 365 tenant open the exchange admin center and click mail flow and click connectors. If you re confused about what smtp is click here to jump down to the section where i ve explained it. After you ve got that background you can come back here to set things up.

To set up an smtp relay you must first create a connector in office 365 to accept smtp transactions. 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. I configured an imap smtp client with thunderbird working perfectly. Our mail system was migrated from a local exchange server to office 365.

This is my first post as a new sys admin. Senders are not bound by the 30 messages per minute or 10 000 recipients per day limits. Before you attempt to create a connector be sure your account has the proper exchange online permissions. A common reason for issues with microsoft 365 or office 365 smtp relay is a blocked ip address.

Use a dedicated relay connector to send emails through the office 365 smtp relay. I configured openerp with a google account works perfectly the only emailserver not working seems to be office 365 but as a standalone client using smtp not native exchange protocol i guess the issue is not at the microsoft offering.
