=====
12:00:00 ERROR: [4978-24-130-8004010F] Unable to migrate attachment 'AttachmentName.txt' for message:

The possible causes of this maybe the following:

- Anti-virus is scanning the TEMP directory to where the the tool stores attachments during migration preventing them from being written to disk

- The attachments are corrupt

- The attachments are not linked to existing content

 - Confirm that anti-virus is not scanning the temp directory, or turn anti-virus off. Also check the windows event logs and anti-virus logs to see if there has been any activity against .att files and the TEMP directory

- Try opening up that mail and attachment in Groupwise then save to disk. If this does not save, the attachment is corrupt. Then run gwcheck to remove any corruption or archive the mail which also removes corruption
