M365 sending mails over smtp

drmedner

Dear All,

I would like to send my newsletter via smtp.office365.com
The same settings are working with the native joomla config and were tested with another tool.
But when I try to send a test email via acymailing config, I will not receive anything.
A test mail via phmail comes through.

These are my settings:
Server: smtp.office365.com
Port: 587
Sichere Methode: SSL
Aufrecht erhalten: yes
Authentifizierung: yes
Benutzername: *
Passwort: *

How can I solve my problem?

Hi,

Changing your config from SSL to TLS will probably solve your issue.

If that doesn't make a difference make sure you are sending your mail (from address) from the same mail address as the one belonging to the mail accouunt you are logging in to. In case you need to send mail from different mail addresses belonging to your domain you should setup a smtp relay. It's all documented here: https://docs.microsoft.com/en-us/exchange/mail-flow-best-practices/how-to-set-up-a-multifunction-device-or-application-to-send-email-using-microsoft-365-or-office-365
