Hello,

I am having a connection issue with Outlook when I try to use the Outlook node. The emails are not being delivered, as if they were being treated as spam. Has anyone else experienced this issue?

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Hi @Tom_Lehmbecker ,

Welcome to the community! :sunflower:

I just gave this a try and indeed my email was sent straight to the receivers spam folder.
However, this is not something n8n can control and is more related to the email provider rather than the node. For example, when I ran the same workflow with Send Email my message wasn’t flagged as spam.

You can check the spam of your email account using this tool: https://www.mail-tester.com/ - it also explains which factors affect your spam score and how you can improve these.

In this case you could either tell the receiver to allow emails from your account so they can overwrite the spam blocking or, if you’re sending emails to multiple receivers, I would go over the details given by the email tester and try to improve your domain’s “reputation” and try out different email nodes as well.

Hello,

Thank you for the response, but my email address is correct; I have tested it. Does the Microsoft module use a generic address to send emails from the flows?

Perhaps the issue is that my Microsoft account does not accept connections from your IP address?

Remote server returned ‘550 5.7.708 Service unavailable. Access denied, traffic not accepted from this IP. For more information please go to Email non-delivery report (NDR) and SMTP errors in Exchange Online - Exchange | Microsoft Learn AS(7230) [PASP264MB4744.FRAP264.PROD.OUTLOOK.COM 2024-06-19T16:44:33.448Z 08DC8F28A7D9D512]’

hello @Tom_Lehmbecker

have you tried to send the email directly? The n8n actually doesn’t affect the sending behavior, it uses the MS graph capabilities for sending.

Hello @barn4k ,

When I send an email directly, it works without any issues. However, I checked my Office365 connection logs and the connection attempts to Exchange Online from n8n are failing. I think I need to create a security policy that accepts this IP address.

@mariana-na can someone help guide us? Also having this issue, only happens via N8N, works fine with Graph API via powershell, or sending via OWA, so what’s different about N8N?
