What Are the Differences Between Outlook 2007 & Outlook 2010?by James Dalton
Microsoft Outlook 2010 contains many features and enhancements not present in Outlook 2007, such as the Ribbon interface in the main window. Conversely, several features present in Outlook 2007 are removed from the 2010 version. Outlook 2010 is the first version available in a native 64-bit edition.
Outlook 2010 includes the Ribbon interface in the main application window, replacing the legacy drop-down menu options at the top of the main Outlook 2007 window. The Ribbon interface groups common menu items as icons in tabs spread across the top of the window. The Ribbon only appears in special Outlook 2007 windows, such as New Mail Message. The Outlook 2010 interface is similar to all other Microsoft Office 2007 and 2010 programs. Outlook 2007 stands out with its legacy appearance in the main window.
In addition to the Ribbon interface, Outlook 2010 includes enhancements to the message conversation view and gives users the ability to ignore and clean up conversations. Quick Steps is a new feature that lets repetitive multi-step actions be compiled into a single-click button. For example, composing an email message to a particular person can be accomplished with one click. MailTips alerts you when common mistakes, such as composing a message to a large group of people, are about to be made. The ability to resize photo attachments and send a snapshot of your computer screen are useful new features in Outlook 2010. Grouping calendars for multiple people into a single view facilitates scheduling tasks. The new Outlook Social Connector expands the scope of Outlook to common social networking tools, such as Facebook and Windows Live.
The Go menu in Outlook 2007 is replaced with the Navigation pane in Outlook 2010. Microsoft Exchange 2000 is no longer support in Outlook 2010. DAV protocol support to connect to HTTP email accounts is also discontinued. Keyboard shortcuts to the Outlook 2007 menu items, such as Edit, are discontinued because these menus no longer exist in the Outlook 2010 Ribbon interface. The Organize pane and Remote Mail feature are no longer available in Outlook 2010. You can no longer publish your calendar to office.com or save your calendar as a Web page in Outlook 2010.
Outlook 2010 is the first version of Outlook available in a 64-bit edition; Outlook 2007 is only available in a 32-bit edition. Sixty-four--bit computers contain processors that handle large amounts of memory more efficiently, resulting in performance gains. However, all add-ins must also be programmed as 64 bit. For this reason, only install the 64-bit version if it is explicitly required. For example, if you work with Excel files larger than 2 GB, you need to install the 64-bit version of Office 2010 that gives you the 64-bit version of Outlook 2010.
