I’ve been using Mozilla Thunderbird pretty extensively past few months. Even though I do have Microsoft Outlook installed on my work laptop – with the amount of mails that I send and receive, Outlook just dies when the Inbox size shoots up and that’s an absolute killer. One of the problems with Thunderbird is that unlike Outlook, its an email-client, and not a complete PIM suite, and my work requires me to maintain an extensive calender system. But thanks to addons, you don’t have to worry about this. Let me show you how you can convert Mozilla Thunderbird to complete PIM suite.
