Katalon unable to sent reports to desired email address

Despite correctly configured email server I am unable to send reports to desired emails (unable to send test email). Help, please!

Have you followed user guide here?

Yes, it used to work, but after latest Katalon update it stopped working…

It’s working ok for me. I am on version:

Katalon Studio
Version: 5.2.0
Build: 1

Solved! Anti virus has to be disabled!
