outlook - Using Java Mail -

i send email using java application. when press button, there should automatically sent email , somehow didn't find solution yet. found lot of example codes in internet, doesn't matter if use gmail / gmx or outlook, receive message :

"could not connect smtp host: mail.gmx.net, port: 587; nested exception is: java.net.connectexception: connection timed out: connect"

based on domain, host mail.gmx.net or smtp.office365.com etc.. think there's somehow connection problem, wasn't able fix it. have ideas / codes worked ?

thank in advance.
