O365 does not support Basic Auth

[mhoult22]

Hi. I had this task working fine with a Gmail account, but we need to use one of our own company accounts which are on Outlook 365.
I have a generic service connector configured in ADO, but this uses "basic authentication".
With our company email credentials in this connector the send email task is now giving error: Authentication unsuccessful, basic authentication is disabled.

It seems I need to use a task that supports modern auth, but I am using this task to email the test results from our release pipeline and I am unable to find an alternative pipeline extension that can do this.

Please could you advise? Many thanks.
