>> Why GroupWise is not there? Is it not Mail Client program? Also I checked on another computer. It has an entry of Outlook Express, but it was not properly setup there, threfore it would not work...

Yes, I've asked him, but he haven't responded yet. Perhaps due to time difference (what is time in England right now?)
