Outlook opens all attachments.

Hi,

one of our customers has a feature that I didn't know. Let me eplain. If I
receive an email with 2 pics in it and I open the first my built in fax
viewer opens the pic from my temporary internet files. This is the default
configuration. What I can't do is, press the next button and the next pic
will be displayed. It will display other pictures (that I opened before) but
not the next in the mail. It will only open the next if I have opened it
before so that a copy is saved in the temp folder. That's what I thought it
is the way it works.
But now I found a customer that clicks on a pic and if he presses 'next' the
fax viewer will show the next pic (attachment). After that we asked the
customer to delete the temp folder and open one pic (the first attachment).
All 4 attachments were extracted to the temp folder. I think that this is
not very secure. So where does this come from?

The customer uses Outlook 2003 (without SP1 I think). I also know of Avant
Browser that is installed on some systems.

Maybe they are receiving in a TIF format that permits multiple images
per file. For example, if you use the ZIF (Xerox's TIF file format)
with the Pagis Viewer (http://www.callwave.com/faxline/exe/viewer.exe)
then you can see multiple pages per TIF. Obviously the sending fax
service must use that TIF format for there to be multiple pages within
it to view. I would expect other viewers, like XnView and IrfanView, to
handle ZIF files. I remember that Callwave (via Faxwave) could be
optioned to send you ZIF files instead of normal TIF files. I now use
eFax but it has been way too long since I received a fax via e-mail from
them to know if their .efx file also supports multiple pages per file.
If one file format can permit multiple pages per file then I would
suspect other file formats might also provide the same feature. Could
be the customer is using Pagis Viewer, or eFax's viewer, or some other
graphics file viewer. You didn't say. Maybe someone who knows what
viewer you are asking about might know how it works, whether it is
displaying multiple images stored within one file or somehow retrieves
the separate attachment files from an e-mail.

This is how it should work, theoretically. When a message is opened or
previewed, all attachments are written to the secure temp folder (they are
AV scanned at this time, if you use autoprotect) and you are able to use
the image viewer to scroll through the images. Unfortunately, it doesn't
work that way for most people... the only think I can think of is they use a
non-typical sort order, so the next image to be viewed is another one on the
email.

Because only the logged in user can access their secure temp folder this is
considered secure. From the antivirus angle, it's no less secure than any
other method - autoprotect will scan them at the time outlook writes them to
the disk.

because I am not able to answer with google:

Hi,

thx for your answer. So let me clarify this:
- You say that Outlook should open all attachments.
- This is the default behaivor. There is no need to activate this
- There is no extra tool needed

I tried this with different (at home/at work) outlook installations.
- I send 3 messages.
- Each has 2 different jpgs attached.
- Each message has a different message type (HTML/TXT/RTF)
- I deleted the temporary internet files (and the OLK Folder inside) and
restartet outlook

When I open the first attachment only the first attachment is written to
disk.
I found this, this morning:
