For me, MS Outlook (2007) have been the best email client that i have used. I have use it for all my work emails. And i found that it is stable and fast. However, there is one major drawback to Outlook. It is not free. So i look for alternatives. I used to like Mozilla Thunderbird. For awhile at least. I find it to be slower and less intuitive than Outlook. And it does not handle large amount of email messages that well (at least, if compared to MS Outlook). Ok, so to cut the long story short, i am now trying out PocoMail version 4.8. Initial outlook remains good but i am now testing it further to see if it can replace MS Outlook on my future works. Keep you informed !
