Error with Email Tool

[shinyin]

Hi all,

I am having issue with my Email tool as I got error message which I have no idea what is that about.

Error: Email (99): Record#17: Unable to send email: ""

It was running successfully last week (in scheduler) but failed today.

In my Email tool, I disabled the Autodetect SMTP checkbox.

Could you please kindly advice what is the issue?

Thank you.
