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.
