I have a single domain with and Exchange Server 2003. Outlook 2003 is the mail client we use running on Windows XP SP2. Some folks are experiencing some slowness when using Outlook, you can type a full sentence then get a cup of coffee come back and it's still not finished showing all that you have typed. I've run spywares, antivirus scans and shows up nothing. All workstation are updated with patches and updates. Anyone else experinced this issue?

Thanks for your help!
