Keycloak with Outlook SMTP Server Failed to send email

I have keycloak on an Azure Virtual Machine, and until a few weeks ago everything went normal, but for some storage problems I had to restart the server. After that, I can't test the SMTP connection at the Email tab.
If I look the logs, I see:

}
Build COnfig:
compile ":mail:1.0.7"
Hoping for your generous help.

The error message also points to an SSL connection. Seems like you are trying to connect to an SSL port using standard SMTP TCP. Here is a Stack Over flow that has a similar error message.
unrecognized ssl message plaintext connection exception

Make sure you use correct SSL port number. By default SSL/TLS encrypted SMTP uses port 465.

I've implemented a code that sends e-mails using Outlook server (worked fine locally).
What's the cause of the following exception on my production environment and how do I resolve it?

Java Mail Error : java.net.ConnectException: Connection refused: connect

I am stuck with the mail sending with Java Mail API.
I am not able to connect SMTP server with any kind of properties... I have tried with different combination.
I am connecting SMTP Remote server (Server is not at localhost, its in LAN), with port 25 but it gives me the port error to 465, I dont know why ?
javax.mail.MessagingException: Could not connect to SMTP host: *RemoteIP*, port: 465; nested exception is: java.net.ConnectException: Connection refused: connect
If anyone can help.
Thankx in advance.

Maybe your mail server is actually using SMTPS on port 465 (although it's not the recommended port). If that is the case you can see here an example of using JavaMail with SMTPS. Note the property mail.smtps.host; you also have the mail.smtps.port property to specify 465.
