Sending email using katalon studio

im trying to send an email using outlook and im getting this error


are you sure that correct port is 25?
try to change different protocol

as @Timo_Kuisma suggested,double check in your outlook account for the right settings. 25 is for unencrypted protocol, cannot work with TLS

check also the url. as far as i remember, the smtp server will be different in outlok when using encrypted vs unencrypted

thanks alot
