From home, I am connected to the company exchange server via cable
vpn. If I click on a row in the inbox list that has a large
attachment, outlook takes a long time to respond. I am NOT trying to
read or download the attachment, I just want to read the body. It
almost appears that outlook is downloading the attachment to some temp
area.
Is there any way to configure outlook to respond the same whether or
not there is an attachment in the email?

When you click on the message, it's going to try to open it in the preview
pane (or, if you double click, it will just try to open it) - this includes
the attachment.
Version of Outlook?
Using OL2003 in cached mode via RPC/HTTPs? If so, you can configure it to
download headers only until you wish to download the entire message.
 
First, I am NOT double clicking on the message. I am just using the
down arrow or single clicking on a message. If the message has an
attachment when I down arrow, Outlook pauses for a long time (5-15
seconds).

I am using 2003 Outlook and cached mode is NOT set.
I'm not sure what "RPC/HTTPs" is that you mentioned. Under the email
account I just see a check box [] Use exchange cached mode.
Should I use this mode? If so, what is the downside of using it?

Thanks,

Generally yes, you should use cached mode. It's faster, especially over
slow connections. Downsides? Occasional sync traffic. More local disk
space used.

Upsides? Enables the Outlook Junk E-mail filter, faster performance over
slow connections.

Okay, so does that mean that you do NOT have the Preview pane open to show
the e-mail content of a message when you select it? If the Preview pane is
open, you ARE downloading each message that you select (Outlook will default
to selecting the first one in the message list pane when you load it). If
you have the Preview pane open, well, then any message you select WILL get
downloaded because obviously you cannot view a message without opening it,
and opening it means downloading it. Attachments are not some link to a
file on some file server. Attachments are *IN* the e-mail so downloading
the e-mail means you download all of the body of the message and that
includes the attachments that are in the body of the message.

If you don't want to download the bodies of the e-mails when you select them
and only want the headers then configure Outlook to only get the headers
(download description only). Then you'll have to mark each item that you
want to fully download and then have to perform the operation to actually
download them (download marked items).

Having to mark which items you want to download and then manually start the
download of marked items makes mail a much more manual task as opposed to
having the e-mail client poll for mails. It would be far easier if you
stopped trying to use e-mail as a substitute for FTP. E-mail has no resume
capability, is slow because of bandwidth throttling, is unreliable, doesn't
provide for error correction, and has other problems. Stop using e-mail for
file transfer.

You might also disable e-mail scanning by your anti-virus software since
this is unnecessary, duplicates the on-access scanner, and will delay e-mail
delivery and cause timeouts. Your AV software has to interrogate your
inbound e-mails looking for viruses. Meanwhile your e-mail client is
waiting for a response from its RETR command to get the message and can
timeout if the AV program doesn't deliver something to the e-mail client
while it scans the message.

Since attachments are IN the body of a message, you can't read one without
downloading the other.
 
Confused??

Yes, I am using the preview pane.

As far as the attachment being part of the email, There must be a way
to beat this. I have a PocketPC Phone. On it I installed an email
reader "Profimail" from lonelycat games. I am using imap to connect to
the exchange server. I have it configured to download up to 10K of the
body of the message. On a message by message basis, I can selectively
download an attachment. The MS email on the PPC can limit the
download of the message size, however you can get all attachments or
non.
Either way both of these programs can break out the attachments on a
PPC, so why can't Outlook do the same?

Meanwhile, I switch to cached mode and that appears to work much
better for me.

Your pocket mail client is using the TOP command to retrieve the headers
along with the first N lines specified in the "TOP <msg> <N>" command that
it sends to the POP3 server. Mail monitor utilities do this all the time.
They will send "TOP msg 0" to just get the headers. If you configure them
to retrieve the first 10 lines of the body then they send "TOP msg 10" (msg
is the number of the item in the mailbox). If you enable the transport log
in Outlook, you can see what POP3 commands are being sent when Outlook
queries the POP3 server for a list of items and retrieves their headers or
their entire body (headers and body).

You mentioned IMAP but I haven't used IMAP but the transport log should show
you those commands, too. You can read up on the IMAP commands at
ftp://ftp.rfc-editor.org/in-notes/rfc2060.txt. From a cursory scan of the
doc, it looks like the FETCH does double duty to retrieve just the headers
or the entire message (according to the <section> parameter).

Did you try disabling e-mail scanning in your anti-virus software? Maybe it
is forcing a FETCH of ALL to retrieve the messages so it can scan them for
viruses.

Sounds like disabling cache mode worked for you. Sounds weird, like the
IMAP server is configured to recognize the client wants cached mode. Cached
mode means you download a copy to have a local copy available, and that
means the message gets downloaded to your e-mail client. Sort of defeats
the purpose of using a standard IMAP server.
