Verizon Webmail Investigation

Does anyone know what search strings to use when searching for Verizon webmail remnants?

Also,

When keyword search terms are found in pagefiles, unallocated space and ".dat" files what is the best method for rebuilding/recreating the webpages? I have used HTML Carver in the case processor to get some HTMLs with success, however, I have a large amount of hits in the pagefiles, unallocated space and ".dat" files. This data isnt as neatly formed as the data extracted by the HTML carver, but there is definitely useful data. What method is best for producing this data? Even if I could extract the webmail remnants to a text file that would be sufficient.
