Microsoft 365 - 550 Issue

How To
1

Hey all,

I hope you can help me with that! I am using a Outlook 365 essentials plan and connect it via the module to send a mail after a trigger was fired. The make.com automation runs perfectly fine, but I always receive a mail with the following content:

I have already checked all the setting:

  • DNS
  • SPF
  • DMARC
  • DKIM

Everything seems to be working fine. Outlook is trying to send the mails, but I always get the issue as mentioned above.

Does anyone have ideas?

Thanks in advance!

Welcome to the Make community!

For technical issues or bugs like this, directly contacting support can often lead to a faster resolution. They have access to your specific account details, scenario and scenario logs, server-side logs, and internal tools and resources, which allows them to investigate more thoroughly than what you have access to. Additionally, sharing sensitive information about your account or scenario might not be suitable for an open forum discussion.

You can open a new ticket here, or if you are unable to login for some reason, you can create another new free account to access the ticketing system (which is only available to logged-in users). After submitting a new ticket, you will receive an automatic confirmation email with the subject “Ticket Created” in the subject. If you do not receive this, try sending the ticket again.

If you manage to get your issue resolved with support, we’d still love to hear about it! Sharing your solution on the forum can help others facing similar problems.

Hope this helps! Let me know if there are any further questions or issues.
