Ah. If you're previewing the message then yes, I think it does "download"
the attachment to the temp folder in anticipation that you're going to want
to see it.

Unless/until you select/preview the message the attachment won't be
downloaded if you're not in cached mode.

thanks, do you know if this behaviour is different in Outlook 2007? I
have a hosted Exchange. My primary mailbox is cached (Cached Exchange
Mode on), and I have an additional mailbox open (online mode). When I
click on a large message in the additional mailbox (to preview it in
the Preview Pane), Outlook 2007 seems to download the text +
attachment. Example - a small message (text only) displays almost
instantly in the Preview Pane. A message with a large attachment (e.g.
3MB) (and small amount of text) takes 40 seconds to preview. I can
only speculate that the entire message is being downloaded in Outlook
2007, even though I am just previewing the text in it.
