So I dont have Microsoft Outlook. Is there a free alternative ?

Thunderbird : Solution from Mozilla labs, it is one of my favorites. Can be configured for pop3 and imap. Quick to setup and I really like the simplicity of the whole interface. Unlike outlook, it doesnt have integrated calendar, but calendar application can be downloaded from Calendar project page. The calendar can be integrated with the application.

Foxmail : Since the website is in chinese, I couldnt really test it out in real time.

Dreammail : [The website has been down for quite a few days so I havent really checked it out. If this continues I will remove this from the list]

Evolution :  [Linux only]

Courier :

gmail : My personal favorite apart from thunderbird. You can configure it to receive pop and imap emails. You have integrated google docs – keep your work online, download as PDF etc, integrated google calendar and much more. I think it also allows you to login via https connection. Although it is really a commercial solution (ads and all) , they dont interfere really with work and I really like the option to open the documents in google docs, edit them and download or resend them. Document sharing becomes easy as well.
