    Thanks for your post.

    Please send the detail log (zipped) to Support (support@advansyscorp.com), which you will find in the target archive folder.

    We had a few reports about this issue and most cases it was resolved by following one or more of the tasks listed in this feature topic:
    Troubleshooting Export Problems

    Especially the following items:


    • Create a new folder and move potential problem messages

      Part of the GroupWise data store may become corrupted. Experience has shown that moving potential problem messages from one folder to a newly created folder can force a rewrite of the data store, which may rectify the access problem. After moving the messages from the ‘problem’ folder, you may need to delete it.

    • Folders which contain more than 5,000 messages

      If you are having problems exporting folders which contain a very large number of messages, try splitting the folder into new folders which contain less than 5000 messages each.

    It is probably also a good idea to update the GroupWise client from 8.0.1 to the latest patch release. After making the above changes, please do a thorough GWCheck (Fix Structure and Contents) before retrying the export.

    Hope this helps.
