Microsoft Office for Mac 2011 is a version of the Microsoft Office productivity suite for Mac OS X. It is the successor to Microsoft Office 2008 for Mac and is comparable to Microsoft Office 2010 for Windows.
Microsoft Office 2011 includes more robust enterprise support and greater feature parity with the Windows edition. Its interface is now more similar to Office 2007 and 2010 for Windows, with the addition of the Ribbon. A new version of Outlook, written using Mac OS X's Cocoa API, returns to the Mac for the first time since 2001 and has full support for Exchange 2007. It replaces Entourage, which was included in Office 2004 and 2008 for Mac. Support for Visual Basic for Applications macros returned after having been dropped in Office 2008.
In addition, Office 2011 supports online collaboration tools such as Windows Live SkyDrive and Office Web Apps, allowing Mac and Windows users to simultaneously edit documents over the web.
Office for Mac 2011 has a number of limitations compared to Office 2010 for Windows. Two editions are available to the general public. Home & Student provides Word, Excel and PowerPoint, while Home & Business adds Outlook and increased support. Microsoft Messenger 8 is included with both editions, and Microsoft Communicator for Mac 2011, which communicates with Microsoft Lync Server, is available only to volume licensing customers. Office 2011 requires an Intel Mac running Mac OS X 10.5.8 or higher.
