Unable to get SMTP working with M365

Unable to get SMTP working with M365

Good Morning,

I have found the below post

https://moodle.org/mod/forum/discuss.php?d=410567&mode=2

I have tried to replicate the settings, but I have matched the settings as per the above post but nothing works.

Our tenant has MFA enabled so I have on a particular user enabled Authenticated SMTP and an app password on one of my users as well as a connector to allow traffic from the servers ip to use the SMTP relay.

I am on moodle 4.4+

I am not sure why these settings arent working as I have this same kind of setup being used on another M365 tenant and with different software and its working as it should be.

Any help would be greatly appreciated.

Not a Windows person, but since nobody replied, trying from first principles.

  • SMTP hosts = smtp.office365.com:587
  • Security = TLS
  • Auth type = LOGIN
  • SMTP username = same as support email
  • Pass = the password
But nothing works. How does "nothing works" look like. Something freezes or screens go white or throws errors?

- Did you try yoursite/admin/testoutgoingmailconf.php ?

I'm not sure whether Debugging logs the SMTP dialog. There was a third-party plug-in to get the full trace of the SMTP dialog.

- Dumb question: Did you check for firewall issues? This is what I see on my laptop:



P.S. All that said, notice that the post you are following is almost 4 years old. Unlike the Internet standards (RFCs and all) the services from the BIG are completely in their hands. The make and shake them at their will. Hope a Windows colleague will confirm that the post is still valid, or come with a newer tutorial.

Hi Thanks for this feedback.

I am using the M365 App password on my mail account the support email we have setup is a shared mailbox.
 
I have the settings exactly as you show, but to no avail

When I run the testoutgoingmailconf.php it gives me an error - Your site couldn't communicate with your mail server. Please check your outgoing mail configuration.

firewall is fine here.
