Unable to Configure Outlook email server

I’m trying to use an outlook email account as email server for mattermost but I can’t get it to work.

Server: smtp-mail.outlook.com
Port: 587
Authentication Enabled: true
Username: [email address]
Password: [password]
Connection Security: STARTTLS

Testing fails with:
Failed to authenticate on SMTP server [details: 504 5.7.4 Unrecognized authentication type [CWXP265CA0055.GBRP265.PROD.OUTLOOK.COM]

Is it possible to use outlook at all?

UPDATE: I just updated to 4.6.0 and this issue persists.


Hi @RbDev,

Thanks for your question,

Would you be interested in looking at the Outlook Integration for Mattermost?

I also found this forum post about a similar issue - not sure whether it helps?
