Just to let you know I solved this issue and the contents of the table are Microsoft OLE encoded OLE File format info I now have an extraction method that recovers Documents, Emails and Emails attachments stored this way.
The scripts are using a number of system tools and third party Java library's controlled via Talend. However I can't give too much away as to create these has taken a significant amount of time and effort.
If you want more info please get in contact directly.
Cheers
