Email, Exchange, Thunderbird, Attachment Truncated in Thunderbird, Attachment size incorrect
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
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.
The steps to fix this in Thunderbird:
- Open Thunderbird.
- Select Preferences.
- Select Advanced.
- Select Config Editor.
- Accept the warning.
- Enter "chunks" in the search box.
- "mail.server.default.fetch_by_chunks" appears.
- Double-click so Value reads "false".
- After changing this setting you will need to remove and reconfigure you Exchange account on Thunderbird per the instructions listed here: Office 365, Email, Exchange, Thunderbird
