I am using Microsoft Office Outlook 2003 on my Windows XP computer. I am using a limited bandwidth connection from my ISP. For this reason I want to make the optimium use of my network bandwidth. I sooner came to know that Outlook have a "Process all marked headers" kind of feature which can help you in your internet optimization. So I am here to collect as much information as possible about this feature. Can anyone tell me how to use "Process all marked headers" feature in Outlook?
