Meraki automation SMTP target not working

Not sure if this is the correct board as there isn't a specific one for the new automation feature...

 

I've setup a SMTP target pointed at the Microsoft O365 direct send endpoint for our org but it's failing with the following error (I've changed out the IP address - the actual error has our email address in it):-

 

{
  "output": {
    "error": {
      "code": "400",
      "message": "action execution  errored for type email.smtp_send_email err:code:400 message::dial tcp 0.0.0.0:25: i/o timeout"
    },
    "response": {
      "elapsed_time": 15.048816412,
      "end_time": "2025-10-13T14:28:30.56Z",
      "start_time": "2025-10-13T14:28:15.511Z",
      "succeeded": false
    }
  }
}

 

I've raised a support call but I don't think they even knew about this new feature as they kept asking me which network it related to, and to do a capture of my browser session.

 

Does any one here have any ideas or do I need to wait for the escalation?

Can you or someone check the 365 logs, they might be more elucidating? Are you able to test with any other smtp relays or services?

I bet it is Office 365 is blocking it.
