Using OAuth for Outgoing Mail - Office 365

[Patrick Schneider]

Hi,

for using Office 365 we want to change to OAuth for outgoing Mail. How can i set up this? I only find the SMTP Settings for Basic Auth, which will be discontinued in Oct 2022 (https://docs.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online).

Hi Patrick, here's a good start:

Thanks Karel, thats for incoming Mail (which is already set up). We want to configure outgoing mail as well.

Oops :-) We run a local SMTP server that - I think - acts as a bridge between the client (Jira) and the Office 365 relay. I can check for more details if you want to...

[Patrick Schneider]

That would be fine. You use Postfix?

[karel_mellen]

Just asked. We use an internal IIS server which forwards the email to the online SMTP relay at Microsoft. All this without authentication; but the online relay does check the origin IP - basically checking that outgoing emails are coming from inside our organisation.

HTH, Karel

Thanks for this.
