How does Exchange work as far as the clients are concerned? I have two machines, which I believe are under powered but my boss believes otherwise, that are slow at receiving mail. It is only these two machines having problems, everyone else is fine. One machine is a laptop, P4 processor w/ 256MB of memory with WinXP Pro. The other is a P2 400mgz w/ 256MB which is a desktop. The desktop is slow at loading Outlook (the processor peaks out) while the laptop shows no problems with speed. Our exchange server runs a firewall as well as Norton AV and is a Compaq Prolient ML330 G2, it runs ISA server as well. We have about 30-35 people running Outlook at all times. The problem is basically: These two people (especially the desktop) take a long while (30 minutes) to receive a piece of email that was sent in-house. For me, I receive it spontaneously however they do not. The time stamp on the email shows it was sent 30 minutes ago. How would a single piece of email take so long to get from the server to the desktop? How does the Exchange protocol work? From what I understand it pushes email to the client yet still keeps it on the server. Is their somewhere I can go to read how it works? I tried google, but could not find what I was searching for. :-/ If this person has a big (115MB) email folder size, could this be the issue? If so, then why isn't everyone else effected? Any suggestions are greatly appreciated! Thanks! ---------------------------------- --Kenny Mann
