What are Office Web Apps? - Office Web Apps is the online companion to Word, Excel, PowerPoint and
OneNote applications that allow users to access documents from anywhere, whilst offering you the
opportunity to concurrently share and work on documents with other online users. These applications
are now built into the web browser, allowing users rich fidelity of documents anywhere, anytime and on
The Applications allow users to view, share, and work on documents with others online across personal
computers, mobile phones, and the Web without compromising document reliability. They permit the
creation of new documents and provide basic editing capabilities using the standard Office interface.
Office Web Apps are available to business customers with Microsoft Office 2010 volume licensing and
document management solutions based on Microsoft SharePoint Server 2010. Microsoft Office Web
Apps within SharePoint means multiple users can access, edit and save your documents from anywhere
at any time.
Currently there are four familiar members of the Microsoft Office Web Apps family - Word, Excel,
OneNote and PowerPoint:
- Microsoft Office Word – The web apps version works just like the standard version of Word.
You can edit existing documents and save them to SharePoint, making them available at all
times. Not all editing capabilities are currently available within Word Web Apps, but edited
changes are preserved in the original document and are reflected after saving. You can also
search a word or phrase and this will be highlighted throughout the document wherever it
- Microsoft Office Excel - The web apps version can be accessed from any location and
documents can be viewed, created and edited and then saved to SharePoint 2010 to facilitate
the distribution and sharing of the document.
- Microsoft Office OneNote – The OneNote Web App uses the same rendering engine as Word,
meaning that the same rich editing experience is available to users. Real-time collaboration is
supported, with persistent updates. Collaborating in the Web App does not require a
subscription to the notebook (as with the client version). Simply share the SharePoint link to
- Microsoft Office PowerPoint – The PowerPoint Web App has been designed as a companion to
the PowerPoint desktop application. The desktop application is great for creating presentations
and for giving presentations that take advantage of the full power of the local machine. The
Web Application is focused on giving you access to your presentations wherever you are, quickly
and easily. The Web Apps version supports hundreds of editing features and provides you with
a fast and streamlined editing experience, optimised for making simple changes on the move.
The PowerPoint Web Apps provides the highest level of functionality of all web applications. All
core animation types from the client are replicated, it contains the same image fidelity as the
client and the save function is automatic and persistent.
The functionality provided by the PowerPoint Web App, also enables the PowerPoint Broadcast
Slide Show feature. This is a new feature in Microsoft Office 2010 that enables presenters to
broadcast a slide show from PowerPoint 2010 to remote views who watch in a Web browser.
(for a summary of this new feature for SharePoint system administrators and IT Managers
please visit http://go.microsoft.com/fwlink/?LinkId=166102&clcid=0x409).
All of the Microsoft Office 2010 Web Apps have the Ribbon functionality, as well as the in-line Web
Edit and live preview functionality, once again simplifying your portable needs for Microsoft Office
2010. The Web Apps allow you to edit documents at the same time as another user, with live
tracking and automatic saving of changes that are made by each person.
By making Microsoft Office Web Apps so similar to the Desktop App it ensures that users are able to
keep their documents updated from either Application. Having the same features and functions on
the Web Apps guarantees full dependability.
Some simple tasks...
- Adding, re-ordering and deleting of content - this works just like the Microsoft Office
Desktop applications. For example, in PowerPoint Web Apps, when adding a new slide, all of
the layouts in the presentation are available for you to choose from. So if you’re working
with a presentation created from a corporate template or one downloaded from Office
Online, you’ll be able to use the custom layouts from the template.
- Text editing - You can make most common changes to text in placeholders – font, size, and
colour, to name a few. As described above, you’ll notice that when you make changes to text
that has advanced effects applied (reflections, shadows, etc.), those effects are maintained
with full fidelity and are automatically reapplied to the edited text.
- Pictures - Microsoft have made sure that you can not only insert and delete pictures, but you
can also easily apply the same Quick Styles found in the Desktop Application.
- Saving files - As you save your files through SharePoint, this automatically updates the clone
file that is saved on your desktop app, and vice versa, meaning that all files are constantly
backed up in real time. This means that other users can instantly view changes on without
you having to re-send a new version
Understanding Office Web Apps deployment: Installing Office Web Apps on SharePoint Server 2010
adds the Word Viewing Service Application, Excel Calculation Service, and PowerPoint Service
Application to the list of available SharePoint shared services. Additional SharePoint Services are not
required to edit in Word or for OneNote files. Installation also provides a series of web pages and
handlers, each used by the Word, Excel, PowerPoint and OneNote Web Apps.
Which web browsers do Microsoft Office Web Apps support? Microsoft Office Web Apps are
designed to display your documents locally, in the browser, using standard browser objects such as
Explorer, Mozilla Firefox and Apples Safari.
Why can’t I see all of the Office Web Apps functionality? Some functionality of Microsoft Office
Web Apps will not be released until the official release of the 2010 wave of products i.e. current
functionality available in Office Web Word Application are now limited to viewing, searching the
documents, printing and scanning through documents quickly.
How quickly will Office Web Apps load a document? A 1.7MB Word Document with 29 pages of
text, complex tables and numerous images will load in under a minute.
How will Microsoft offer Office Web Apps? When Office Web Apps goes live, Microsoft will be offering
them in three ways:
1) Free to users of Windows Live
2) Running on hosted-SharePoint from Microsoft Online along with subscription fees
3) Running on SharePoint inside the enterprise licensed for use by users who have the desktop
versions of Office.
