A principal tool that you can use in troubleshooting is the Archive directory. This queue is used to archive messages flowing through the GroupWise connector, primarily to capture damaged messages. You can enable the Archive directory to troubleshoot when users aren't receiving messages, are getting non-delivery reports (NDRs), or are receiving corrupted messages.
