Presently we are sending emails (Office 365) from database using UTL_SMTP.
Now as microsoft is going to discontinue basic authentication for SMTP, POP, IMAP etc., and forcing Modern authentication - OAuth 2.0,
how we authenticate using OAuth through existing PLSQL procedure which is using UTL_SMTP.

Hi,

it depends on whether you already have an access token that you can use, or if you need to establish the full credential flow from the RDBMS.
In either case, UTL_SMTP.COMMAND allows you to send an AUTH, XOAUTH2 command followed by the access token. That takes care of the SMTP part.

If you need the full credentials flow, the best option is to use ORDS. In the relevant versions it has native OAUTH2 support packages. Use ORDS to get an access token, and the SMTP commands as indicated by Microsoft.

Regards,

Arian

Hi,

<< the best option is to use ORDS. In the relevant versions it has native OAUTH2 support packages. Use ORDS to get an access token >>

But how we can use ORDS (and packages supporting OAUTH2) against real authentication service we have to use, that is Microsoft Identity Platform ?

I suppose that OAuth2 of ORDS has its own authentication service ...

Thank you for reply.

hi do you have an example of how you send a token using UTL_SMTP ? I already have the token but can't find a way to connect with the smtp.office365.com server using oracle as the only authentication method accepted is XOAUTH2
