Dear @Misjel,

I tried to configure the "controller --> mail server" with outlook smtp server (same settings as in other software that send e-mails).

I'm getting failed messages with sending test mail.

 

I tried with gmail and then getting "critical security notification" from google that says "attempt from unsafe application" and attempt is blocked.

When i allow unsafe applications in google the mail can be send from the controller.

 

Seems like the e-mail integration is not ok? 

I wan't to use outlook as smtp server. Is this not possible?

Please upgrade the controller to the newer version 4.2.4 and check again.

You may also refer to this FAQ to ensure the mail server is configured well.
