I am trying to configure the outgoing mail server. I tried google and it works fine but with outlook.office365.com it doesn’t work. The connection test is successful but when I send a message to a client, in mail setting I see that it was failed and I get this error message:
Mail Delivery Failed
Mail delivery failed via SMTP server 'smtp.office365.com'.
SMTPDataError: 550
5.7.60 SMTP; Client does not have permissions to send as this sender
I tried None, TLS and SSL, different port numbers (25, 465, 587, and even 993 and 995) and different URLs (outlook.office365.com and smtp.office365.com) but no luck. I read somewhere that I need to create a new connector on my exchange mail flow but I don't know what is the exact required configuration since I'm using Odoo Live.
I found this tutorial and configured the relay required for communication with smtp server. Guess what? new error message. smtp auth extension not supported by server
