2009年9月18日，Windows Live 团队在其官方博客更新日志，宣布Office Web Apps进入技术预览版内测，同时也意味着Office正式加入到Windows Live。
Today is a real milestone for people who use Microsoft Office or Windows Live. Starting today, a select group of SkyDrive customers will be invited to try out a technical preview of the online versions of Microsoft Office Excel, Word and PowerPoint, also known as the Office Web Apps, integrated right inside their Windows Live SkyDrive experience. Over time, as the final version is released, the Office Web Apps will become available to all 500 million+ users of Hotmail, Messenger and other Windows Live services.
今天对于使用微软Office或者Windows Live的用户来说是一个具有里程碑意义的一天。从今天开始，经过挑选的一部分SkyDrive用户将会得到邀请加入到在线版Word、Excel、Powerpoint，也就是整合进Windows Live SkyDrive 中被称作Office Web Apps的技术预览版内测当中。过些日子，等Office Web Apps正式版发布后，所有使用Hotmail、Messenger以及其他Windows Live服务的超过5亿用户就都可以使用了。
While the tech preview doesn’t have all the cool features that will be available in the final offering, it does show off the exciting potential of having online versions of Excel, Word, and PowerPoint, and how you can easily access and work with your Office documents from anywhere with an Internet connection.
技术预览版并不包含正式版中的所有功能，仅仅是展示使用在线版Word、Excel、Powerpoint激动人心的潜在功能和如何通过网络轻松便捷的处理Office文档。
When those of you participating in the Tech Preview upload or create a new document, you’ll be able to view them much like you do today when using the full Office programs—without the loss of formatting or data and with the familiar Office 2007 ribbon. And it will be very easy to share your documents in password-protected folders and give permission to whoever you want to have access – just like with any other SkyDrive files.
参与技术预览版内测的用户上传或者创建文档时，会发现这和大家平时使用的完全版Office软件并无两样，不会丢失文字格式和数据，同时还有类似于Office 2007的操作界面。用户还可以像其他SkyDrive上的文件一样，通过密码来保护文件或者给允许访问的用户开放权限。
Personally, I’m excited that, in the final release of the Office Web Apps, I’ll be able to access Office documents from any PC and then be able to share them, show them, edit them, and collaborate on them with people around the globe. I do a lot of presentations so it will be particularly helpful for giving presentations right from Internet Explorer (or Firefox or Safari). Because I’m kind of an Excel geek, I’ll be able to share my spreadsheets in all their glory – with conditional formatting, charts, and more. In the final release, I will also be able to share notes from OneNote in real-time with others.
就我个人而言，最令我激动的是一旦Office Web Apps正式版发布后，我就可以通过任何电脑访问我的Office文档，分享、展示、编辑以及与全球各地的朋友合作完成他们。我经常做一些展示，Office Web Apps对于使用IE浏览器（Firefox或Safari）展示来说特别有帮助。我是Excel迷，我可以分享包括条件格式化、图表等等在内的许多电子表格超炫功能。等正式版发布后，我就可以通过OneNote与我的好友实时共享贴士了。
Why are we making Office Web Apps available as part of Windows Live?
We all use a lot of different services online – e-mail, social networks, photo sites, video sites, and so on. In many cases, we use more than one service for very similar purposes, using Facebook, MySpace , StudiVZ, Mixi or many others for social networking; Hotmail, Yahoo!, or Gmail for e-mail; Flickr, SkyDrive, FotoLog, or Photobucket for sharing photos.
为什么我们会将Office Web Apps加入到Windows Live中呢？
我们所有人都使用着许多不同的网络服务，比如电子邮件、社交网络、图片分享、视频分享等等。很多情况下，我们会为了同一目的而使用多种服务，比如Facebook、MySpace、 StudiVZ、Mixi以及其他社交网络服务； Hotmail、Yahoo! 或者 Gmail等邮件类服务；Flickr、 SkyDrive、FotoLog或者Photobucket用于图片分享。
That said, there are certain things we really just want one of. I really just want one place for storing contact info, one personal calendar I can share with my family, one primary mail service that also allows me to check all of my e-mail accounts, one place to get updates from all of my social networks, and one place to store, share, and manage my massive and ever-growing collection of photos, documents, music, and videos.
这就是说我们，我们其实只需要其中一种。一个存储联系人信息的地方；一个可以与家人共享的个人日历；一个可以查看多个账户的电子邮件；一个可以聚合所有社交网络更新的地方和一个可以存储、分享和管理不断增长的图片、文档、音乐和视频的地方。
I can get all of that at Windows Live. And now, with the addition of Office Web Apps, I’ll soon be able to go to Windows Live to create, edit, share, and collaborate on Word documents, PowerPoint presentations, OneNote digital notebooks, and Excel spreadsheets – all in high fidelity and all online regardless of which PC I’m using and whether that PC has Office on it.
以上这些我们都可以在Windows Live中实现。而现在，随着Office Web Apps的加入，我们可以即将实现在Windows Live中创建、编辑、分享和合作完成Word文档、PowerPoint幻灯片、OneNote数字记事本和Excel电子表格。需要保证高保真度和联网而无需考虑使用哪一台电脑或者是否安装Office软件。
I’m super excited about today’s release and the future of Office Web Apps. Over time, we’ll add the OneNote Web App to this experience as well as expand both the functionality and the number of people who get to try out the services.
我相当激动的与大家分享了今天发布的技术预览版和未来的正式版。过些时候，我们将把OneNote加入进来并扩展一些功能和参与内测的人数。
