9. Understanding and Using WebReady Document Viewing
WebReady Document
Viewing allows users to view common file types in Outlook Web App
without having the applications associated with those file types
installed on their computer. This allows users to view the following
files:
-
Adobe PDF documents with the .pdf extension
-
Microsoft Office Excel spreadsheets with the.xls and .xlsx extensions
-
Text and Microsoft Office Word documents with the .doc, .docx, .dot, .rtf, and .txt extensions
-
Microsoft Office PowerPoint presentations with the .pps, .ppt, and .pptx extensions
For attachments, the following related MIME types are supported, as
well as related open XML formats for presentations, spreadsheets, and
word processing documents:
Note
WebReady Document Viewing
works by converting documents in supported formats to HTML so that they
can be viewed as a Web page in Outlook Web App. Thus, when an e-mail
message has an attachment in a supported format, WebReady
Document Viewing allows the document to be viewed without having to
first download the document to the user's computer or open a helper
application.
When there are conflicting settings between the direct file, remote file, and WebReady Document Viewing settings, you can force clients to use WebReady
Document Viewing first, if you want. This means that the documents will
be opened within Internet Explorer rather than in a related
application, such as Microsoft Office Word.
You can enable or disable WebReady Document Viewing separately for
public computers and private computers. However, supported document
settings for both types of computers are shared and applied to both
public and private computers in the same way.
To configure WebReady Document Viewing, complete the following steps:
-
In the Exchange Management Console, expand the Server Configuration node, and then select the Client Access node.
-
In the upper portion of the details pane, you'll see a list of your
organization's Client Access servers. Select the server you want to
configure.
-
In the lower portion of the details pane, you'll see a list of option
tabs for the selected server. On the Outlook Web App tab, right-click
the virtual directory for which you are configuring WebReady Document
Viewing, and then select Properties. Typically, you'll want to configure
the OWA virtual directory on the Default Web Site because this
directory is used by default for Outlook Web App.
-
On the Public Computer Files Access tab, use the following techniques
to configure WebReady Document Viewing from public computers:
-
Enable WebReady Document Viewing by selecting the Enable WebReady Document Viewing check box.
-
Disable WebReady Document Viewing by clearing the Enable WebReady Document Viewing check box.
-
Force the use of WebReady Document Viewing first by selecting the Force WebReady Document Viewing First check box.
-
Allow documents with supported WebReady Document Viewing formats to
be opened in related applications by clearing the Force WebReady
Document Viewing First check box.
-
To configure WebReady Document Viewing for private computers, on the
Private Computer File Access tab, select or clear the Enable WebReady
Document Viewing and Force WebReady Document Viewing First check boxes,
as appropriate.
-
On either the Public Computer File Access tab or Private Computer
File Access tab, click the Supported button on the WebReady Document
Viewing panel. The WebReady Document Viewing Settings dialog box
appears, as shown in Figure 9.
-
To allow all supported document types to be used with WebReady
Document Viewing, select All Supported Document Types and then click OK.
-
To customize the supported document types, click Specific Document
Types. Use the following techniques to configure supported document
types:
-
To stop allowing a document extension or MIME type, select it and then click the Remove button.
-
To restore a previously removed document extension, under Specify
Document Extensions, click the Add button, select the document extension
to add, and then click OK.
-
To restore a previously removed MIME type, under Specify The MIME
Types Of Documents, click the Add button, select the MIME type to add,
and then click OK.
-
Click OK to close the Properties dialog box for the virtual directory.
In the Exchange Management Shell, you can use the
Set-OWAVirtualDirectory cmdlet to manage the WebReady Document Viewing
configuration. Set the –Identity parameter to the identity of the
virtual directory on the server with which you want to work, such as:
Set-OWAVirtualDirectory -Identity "Corpsvr127\owa (Default Web Site)"
-WebReadyDocumentViewingAccessOnPublicComputersEnabled $false
-WebReadyDocumentViewingOnPrivateComputersEnabled $true
If you are unsure of the virtual directory identity value, use the
Get-OWAVirtualDirectory cmdlet to retrieve a list of available virtual
directories on a named server, as shown in the following example:
Get-OWAVirtualDirectory -Server "Corpsvr127"
