Hi Mendix Community, We have a project where we are using the Email_Connector Module, we had some conflicts with Jar files and removed them and still had the same issue, in the end removed and re-installed the Email_Connector Module. We are still having a issue when running the send email java action. Main Error Error in execution of monitored action 'RegularClientAction' (execution id: 1724162740120-35, execution type: CLIENT). NoClassDefFoundError occurred for class 'javax/activation/DataContentHandler'. Please make sure the userlib folder of your project includes the correct library which contains this class.
