I have clients who have their email accounts set up in Outlook and Thunderbird, and there is a normal and effective operation.
However, when configuring in other external programs, such as billing programs that have SMTP to send invoices to customers, it always gives this error:

Exception: System error: -2147467259 The requested function is not supported

This error happens in the same way in two different programs.

How can I correct this situation, being that in the old server with Cpanekl / WHM, there was never a problem, so I believe it is a configuration that is not correct.

Regards

Hey there! This looks like a Windows error code, although it's possible there could be something on the server that could be adjusted to resolve this. Can you let me know specifically what software you are using, including the operating system version, and what work you are trying to perform when you get that error?
