Email Attachment Downloads

[RCTOUCH]

hello fellow geekers. I have a question. does anyone know how to have microsoft automatically download all pictures and other attachments when u download email. I hate it when I download email and try to read it on the subway where there is no signal only to realize that I can't view pics or attachments because they wern't downloaded. I have to wait until I have signal and download each attach ent separately. this can be very annoying. thanks
