As I know many of you do, at Asolvi we use Chilkat SMTP with basic authentication (user id & pw) to send out emails via an unattended utility program, reading from the database what to send out.

What I understand from the message info, we might need to change our Chilkat code to use oAuth instead of basic authentication? And that also includes using a web-browser object to collect the oAuth token and save it to the database for future reference.

Is anyone of you aware of this? Should we be concerned about it?

Even if it will continue to work for a while as it does, Microsoft could suddenly turn off the feature of basic authentication after sending a warning email to the customer, that will probably not be read and all of a sudden our support is swamped by angry customers wondering why the emails aren't send no more from our program...

Or have I misunderstood the whole thing?
