it is not Gmail. I am using my organization email(aluri@missionbio.com) but it is through G Suite. Any Idea?

I do not understand this, sorry.

Basically I am trying to send the test execution results to my team but they are not receiving emails. I included the screenshots with the configurations and also the error message. I am using the organizational email address.

Here is the screenshot again. I am using my organizational email. I would appreciate if I can get any help.

This would depend on your network settings. I am not able to help you remotely, sorry.

you should check with your IT guys what are the proper settings to use an e-mail client with your email server
