Email, Exchange, Thunderbird, Attachment Truncated in Thunderbird, Attachment size incorrect

Thunderbird incorrectly reports the size of attachments and truncates attachments from the Exchange servers. I can't open the entire attachment from an email in Thunderbird.

Exchange may mis-report sizes of attachments, so Thunderbird will truncate attachments from Exchange servers unless you tell it to ignore the misinformation, as described on this website: http://forums.mozillazine.org/viewtopic.php?t=628555

The steps to fix this in Thunderbird:
  1. Open Thunderbird.
  2. Select Preferences.
  3. Select Advanced.
  4. Select Config Editor.
  5. Accept the warning.
  6. Enter "chunks" in the search box.
  7. "mail.server.default.fetch_by_chunks" appears.
  8. Double-click so Value reads "false".
  9. After changing this setting you will need to remove and reconfigure you Exchange account on Thunderbird per the instructions listed here: Email, Exchange, Thunderbird
