Hi,
I'm trying to figure out why a forwarded .eml attachment (sent from
Thunderbird, containing email txt) is incomplete when opened in
Outlook 2007. Mail store is iPlanet IMAP. The fwd'd mail and
attachment from Tbird is HTML format.
It appears that when Outlook pulls down the attachment it converts it
to .msg format and truncates all of the inline quoted text, leaving
only the last non-quoted part of the message.
I've tried various "text only" settings in both Tbird and Outlook but
the fwd'd attachment already contains HTML and I don't think those
apply to it.
The only work-around I have thus far would be to ask the senders to
Reply (changing the To: to my address) instead of Fwd from Tbird since
then Tbird places the attached email contents inline. But that's a
poor solution.
TIA,
M

In the case of many AV programs, it is not enough to disable it. You must
uninstall it and then reinstall it without the mail scanning feature.

I'll give that a try and report.
TIA,

Brian, I completely uninstalled the Mcafee AV and rebooted. Same
problem. Open the email in Tbird and the inline quote text is there.
Open the same message in Outlook '07 and I get an attachment which
doesn't contain the inline quote text.
I've also tried setting the "Read all standard mail in plain text"
option in the Trust Center...no difference.
:-(

Messages you've already received won't be corrected, but new messages should
not suffer the same problem.

Hi Brian,
I've done a lot of testing and the client AV is NOT a factor. Which is
a good thing since the AV email scanning isn't something we'd want to
disable. I'd have to check to see if any server-side scanning is in
place (separate department) but if it is, turning it off won't be an
option I'm sure.
Again, it's the "Reply to" message content which retains integrity.
It's the "Forward to" messages that lose the quoted content when viewed
via Outlook, since the earlier message content becomes an .eml
attachment.
In Thunderbird or the web client (iPlanet Messenger Express) both types
of messages display all content. So it appears that Outlook is
truncating the attachment. I also noticed disparate sizes being
reported by Outlook on the attachment name, like so:
Fwd_ Re_ class.newcampaigns GSIP Quick Summary.eml (10.4 KB) (20KB)
Not sure if ^this is indicative of the problem.
For grins, I tried Outlook Express 6. I assume this would also be
subject to the desktop AV scanning (which is enabled) but maybe not.

Why, when there is no technical reason in the world to have it enabled? It
does NOT add to your safety and DOES interfere with Outlook operation.

No, it appears that whatever generates the EML attachment is doing so in
such a way that Outlook cannot decode it properly.

Must disagree there. I've tested with/without the AV email scan enabled
using the EICAR test virus. If enabled, the virus, even with a changed
"acceptable" extension like .zip, gets nuked by the email AV scan and
notifies within Outlook:
Attachment file : eicar.com.zip
Scanner Detected: EICAR test file (Test)
Action taken : Moved (Clean failed because the detection isn't
cleanable)

Exactly my point. The real-time/on-access scanner will catch it. You're
not more protected as you yourself have just described. The infection is
simply caught at a different point in the process. Who'd be foolish enough
to forward a zip file that you weren't 100%% sure about?
