== Platforms ==
Microsoft supports Office for the Windows and macOS platforms, as well as mobile versions for Windows Phone, [[Android (operating system)|Android]] and iOS platforms. Beginning with Mac Office 4.2, the macOS and Windows versions of Office share the same file format, and are [[interoperable]]. Visual Basic for Applications support was dropped in Microsoft Office 2008 for Mac,<ref>{{Cite news |date=August 7, 2006 |title=WWDC: Microsoft updates Universal status of Mac apps |work=Macworld |url=https://www.macworld.com/news/2006/08/07/msuniversal/ |access-date=May 25, 2007 |archive-url=https://web.archive.org/web/20121007070614/http://www.macworld.com/news/2006/08/07/msuniversal/ |archive-date=October 7, 2012}}</ref> then reintroduced in Office for Mac 2011.<ref name="macworld_office_2011" />

Microsoft tried in the mid-1990s to port Office to RISC processors such as [[NEC]]/[[MIPS architecture|MIPS]] and [[IBM]]/[[PowerPC]], but they met problems such as memory access being hampered by [[data structure alignment]] requirements. Microsoft Word 97 and Excel 97, however, did ship for the [[DEC Alpha]] platform. Difficulties in porting Office may have been a factor in discontinuing [[Windows NT]] on non-Intel platforms.<ref>{{Cite news |last=Nicholas Petreley |date=September 3, 1999 |title=Can Linux break Intel's hold on the market? |work=[[CNN]] |url=http://edition.cnn.com/TECH/computing/9909/03/linux.alpha.idg/index.html |url-status=dead |access-date=November 26, 2013 |archive-url=https://web.archive.org/web/20131203012412/http://edition.cnn.com/TECH/computing/9909/03/linux.alpha.idg/index.html |archive-date=December 3, 2013}}</ref>
