Open Source Alternative to Outlook

Microsoft Outlook is a personal information manager available as a part of the Microsoft Office suite. The current version is Microsoft Outlook 2010 for Windows and Microsoft Outlook 2011 for Mac.

Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note taking, a journal and web browsing.

It can be used as a stand-alone application, or can work with Microsoft Exchange Server and Microsoft SharePoint Server for multiple users in an organization, such as shared mailboxes and calendars, Exchange public folders, SharePoint lists and meeting schedules. There are third-party add-on applications that integrate Outlook with devices such as BlackBerry mobile phones and with other software like Office & Skype internet communication.

However, being popular doesn’t mean it is the best. There are several open source alternative email clients that have the same, or even better functionality than Outlook. Let’s take a look.
