Enable the Archive Directory
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.
To enable the Archive directory:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LME-GWISE\Parameters
Note Activating the archive feature and allowing it to continue indefinitely fills the hard disk with archived items. If the hard disk has less than 25 MB of memory left, various services will shut down.
