https://answers.axonivy.com/questions/585/how-can-send-multipart-email-in-ivy<p>Currently i have a problem when send the email with content type is multipart. I don't use Email script to send, i use Java mail to do because i have to add a ICS file content(invitation calendar file) to email header. Actually it can work perfectly if i create a main() in ivy and send it but if i called it by ivy script, it always throw error:</p> <pre><code> UnsupportedDataTypeException: no object DCH for MIME type multipart/mixed; boundary="----=_Part_22_936261044.1395656648093" MessagingException: IOException while sending message IvyScriptMethodInvocationException: Error calling method sendMail(net.fortuna.ical4j.model.Calendar) on an object of class ch.ivyteam.ivy.scripting.internal.language.StaticAccess.
