Hey, Ensure that you have configured your mail server properties properly in the jbpm.cfg.xml the properties like need to be configured at an minimum. also ensure that the mail id's you are using are configured/created in your mail server. | <string name="jbpm.mail.smtp.host" value="localhost" /> | <string name="jbpm.mail.from.address" value=&quot;xyz(a)abc.com&quot; /> | If this is set then every thing should work fine.
