Hi guys, I am looking for recommend for offline email client. So far I only know abt Thunderbird and Window Outlook Express. Is there any other better option out there? Thanks.

If you like to try a betas there is Windows Live Mail: http://get.live.com/betas/maildesktop_betas

And another (I use to use version 5 a while ago) that is quite good is FoxMail 6 Beta5:
