Microsoft 365

Microsoft first announced Office 365 in October 19, 2010, beginning with a private beta with various organizations, leading into a public beta in April 18, 2011, and reaching general availability on June 28, 2011, with a launch aimed originally at corporate users. Facing growing competition from Google's similar service Google Workspace, Microsoft designed the Office 365 platform to "bring together" its existing online services (such as the Business Productivity Online Suite) into "an always-up-to-date cloud service" incorporating Exchange Server (for e-mail), SharePoint (for internal social networking, collaboration, and a public web site), and Lync (for communication, VoIP, and conferencing). Plans were initially launched for small business and enterprises; the small business plan offered Exchange e-mail, SharePoint Online, Lync Online, web hosting via SharePoint, and the Web App with the enterprise plan also adding per-user licenses for the Office 2010 Professional Plus software and 24/7 phone support.{{cite web |first=Julius |last=Motal |title=Microsoft Office 365 Launching June 28th |url=https://www.pcmag.com/article2/0,2817,2386447,00.asp |work=PC Magazine |publisher=Ziff Davis |date=6 June 2011 |access-date=14 March 2013 |archive-date=15 December 2017 |archive-url=https://web.archive.org/web/20171215053602/https://www.pcmag.com/article2/0,2817,2386447,00.asp |url-status=live }}{{cite web|title=Microsoft takes aim at Google Apps with Office 365|url=http://www.networkworld.com/news/2010/101810-microsoft-office-365.html|work=Network World|access-date=15 March 2013|url-status=dead|archive-url=https://web.archive.org/web/20130501200751/http://www.networkworld.com/news/2010/101810-microsoft-office-365.html|archive-date=May 1, 2013|df=mdy-all}} Following the official launch of the service, Business Productivity Online Suite customers were given 12 months to migrate from BPOS to the Office 365 platform.{{cite web|title=BPOS Customers Face Transition to Office 365|url=http://www.pcworld.com/article/231220/article.html|work=PC World|access-date=18 June 2013|archive-date=3 December 2013|archive-url=https://web.archive.org/web/20131203052206/http://www.pcworld.com/article/231220/article.html|url-status=live}}

On March 19, 2013, Microsoft detailed its plans to provide integration with the enterprise social networking platform Yammer (which they had acquired in 2012) for Office 365, such as the ability to use a single sign-on between the two services, shared feeds and document aggregation, and the ability to entirely replace the SharePoint news feed and social functionality with Yammer.{{cite web|title=Office 365 and Yammer integration: What's coming|url=http://news.cnet.com/8301-1001_3-57575193-92/office-365-and-yammer-integration-whats-coming/|work=CNET|access-date=20 March 2013|archive-date=9 November 2013|archive-url=https://web.archive.org/web/20131109112906/http://news.cnet.com/8301-1001_3-57575193-92/office-365-and-yammer-integration-whats-coming/|url-status=live}} The ability to provide a link to a Yammer network from an Office 365 portal was introduced in June 2013, with heavier integration (such as a Yammer app for SharePoint and single sign-on) to be introduced in July 2013.{{cite web|title=Office 365 customers can replace SharePoint newsfeed with Yammer|url=http://www.computerworlduk.com/news/cloud-computing/3452158/office-365-customers-can-replace-sharepoint-newsfeed-with-yammer/|work=Computerworld UK|access-date=12 June 2013|archive-date=19 March 2023|archive-url=https://web.archive.org/web/20230319155700/https://www.computerworld.com/uk/|url-status=live}}

On July 8, 2013, Microsoft unveiled Power BI, a suite of business intelligence and self-serve data mining tools for Office 365, to be released later in the year. Power BI is primarily incorporated into Excel, allowing users to use the Power Query tool to create spreadsheets and graphs using public and private data, and also perform geovisualization with Bing Maps data using the Power Map tool (previously available as a beta plug-in known as GeoFlow). Users will also be able to access and publish reports, and perform natural language queries on data.{{cite web|title=Microsoft Makes Data Mining Self-Service With BI for Office 365|url=http://www.cio.com/article/736026/Microsoft_Makes_Data_Mining_Self_Service_With_BI_for_Office_365|work=CIO|access-date=9 July 2013|archive-date=6 March 2014|archive-url=https://web.archive.org/web/20140306205159/http://www.cio.com/article/736026/Microsoft_Makes_Data_Mining_Self_Service_With_BI_for_Office_365|url-status=live}}{{cite web|title=Microsoft adds business intelligence tools to Office 365|url=http://www.pcworld.com/article/2043844/microsoft-adds-business-intelligence-to-office-365.html|work=PCWorld|access-date=9 July 2013|archive-date=3 November 2013|archive-url=https://web.archive.org/web/20131103102036/http://www.pcworld.com/article/2043844/microsoft-adds-business-intelligence-to-office-365.html|url-status=live}} As a limited-time offer for certain markets (but notably excluding the US), Microsoft also offered a free one-year Xbox Live Gold subscription with any purchase of an Office 365 Home Premium or University subscription, until September 28, 2013.{{cite web|title=Microsoft throws in 12 months of Xbox Live Gold for free with every annual Office 365 subscription|url=https://thenextweb.com/microsoft/2013/07/18/microsoft-will-throw-in-12-months-of-xbox-live-gold-for-free-if-you-buy-an-office-365-subscription/|work=TheNextWeb|date=18 July 2013 |access-date=18 July 2013|archive-date=21 July 2013|archive-url=https://web.archive.org/web/20130721154226/http://thenextweb.com/microsoft/2013/07/18/microsoft-will-throw-in-12-months-of-xbox-live-gold-for-free-if-you-buy-an-office-365-subscription/|url-status=live}}

In December 2024, Microsoft announced that the Microsoft 365 app would be rebranded as the Microsoft 365 Copilot App in an effort to highlight the integration of Copilot features for Microsoft 365 Personal and Home subscriptions.

{{Main|List of Microsoft 365 applications and services}}

The Microsoft 365 desktop applications (formerly marketed as Microsoft Office) are primarily used on personal computers running Microsoft Windows, and are distributed as part of the Microsoft 365 subscription. They are installed using a "click-to-run" system which allows users to begin using the applications almost instantaneously, while files are downloaded in the background. Updates to the software are installed automatically, covering both security and feature updates. These applications were one of the core components of the initial Office 365 service.{{cite web |author=Paul Thurrott |date=2012-09-17 |title=Office 2013: Pricing and Packaging |url=http://www.winsupersite.com/article/office-2013-beta2/office-2013-pricing-packaging-144267 |access-date=2012-11-21 |work=SuperSite for Windows |archive-date=2017-10-26 |archive-url=https://web.archive.org/web/20171026103820/http://winsupersite.com/article/office-2013-beta2/office-2013-pricing-packaging-144267 |url-status=live }} If the user's subscription lapses, the applications enter a read-only mode where editing functionality is disabled.

TechRadar gave the 2013 update of Office 365 a 4.5 out of 5, praising its administration interfaces for being accessible to users with any level of expertise, the seamless integration of OneDrive Pro into the Office 2013 desktop applications, and the service as a whole for being suitable in small business environments, while still offering "powerful" options for use in larger companies (such as data loss protection and the ability to integrate with a local Active Directory instance). However, the service was severely criticized for how it handled its 2013 update for existing users, and its lack of integration with services such as Skype and Viva Engage.

In the fourth quarter of fiscal year 2017, Office 365 revenue had exceeded that of conventional license sales of Microsoft Office software for the first time.{{Cite news |url=https://arstechnica.com/information-technology/2017/07/microsoft-4q17-office-365-revenue-surpasses-traditional-licenses/ |title=Microsoft 4Q17: Office 365 revenue surpasses traditional licenses |work=Ars Technica |publisher=Condé Nast |date=21 July 2017 |access-date=July 21, 2017 |archive-url=https://web.archive.org/web/20190201110644/https://arstechnica.com/information-technology/2017/07/microsoft-4q17-office-365-revenue-surpasses-traditional-licenses/ |archive-date=February 1, 2019 |url-status=dead }}
