I am using Microsoft Outlook through an Exchange Server on Windows 2000. It is constantly hanging up throughout the day. Sometimes it works lightening fast with no problems for a few minutes or a few hours but most of the time, each time I go to do something, anything with the program, it hangs up for anywhere from 30 seconds, to a couple of minutes to endless hanging. I have all the latest update service packs, patches, etc. I have uninstalled, reinstalled, repaired, etc. etc. to no avail. I have completely emptied the entire program of all emails, contact lists, etc and even keeping it empty, it hangs up the same way. I have not been able to find anyone who knows what is causing it or what to do. I need a miracle with this one. Thanks.
