A3 Bad user error when using Mendix app IMAP/POP3 incoming email

Hi everyone, In a project of mine i am experiencing problems when using the "IMAP/POP3 incoming email" module. With this module we want to retrieve emails from Outlook and create Email objects in our application. However this sometimes fails during the "RetrieveEmailMessages" java action. In the logs the following message is returned: 2016-10-10 10:20:43.410 WARNING - Encryption: The string provided is not an encrypted string. Returning the plain string. 2016-10-10 10:20:46.103 ERROR - Encryption: com.sun.mail.iap.BadCommandException A3 BAD User is authenticated but not connected. com.mendix.core.CoreRuntimeException: com.mendix.systemwideinterfaces.MendixRuntimeException: javax.mail.MessagingException: A3 BAD User is authenticated but not connected.; nested exception is: com.sun.mail.iap.BadCommandException: A3 BAD User is authenticated but not connected. at com.mendix.core.component.InternalCore.execute(InternalCore.java:385) Does anyone know what the cause is for this failure? The error seems to happen at random as sometimes the emails are retrieved without errors or failure. Many thanks in advance!

Some voice on internet whisper that this is a bug in Exchange. It seems that your password is wrong.
