WebReady Document Viewing lets users access file attachments in Microsoft Office Outlook Web Access. Users can access common file types such as Microsoft Word documents without having the application installed.
This topic explains how to manage WebReady Document Viewing for Outlook Web Access in Microsoft Exchange 2007.
When you manage WebReady Document Viewing, you can specify files that you want users to be able to access within Outlook Web Access for private and public computers. However, you cannot specify individual settings for only private or public computers.
By default, public computer file access is not enabled for Outlook Web Access. Therefore, when users select the This is a public or shared computer option or the This is a private computer option on the Outlook Web Access logon page, they will be unable to access files attached to e-mail messages.
To perform this procedure, the account you use must be delegated the following:
Exchange Server Administrator role and local Administrators group for the target server
For more information about permissions, delegating roles, and the rights that are required to administer Exchange Server 2007, see Permission Considerations.
In the Exchange Management Console, click Server Configuration, and then click Client Access.
In the work pane, select owa (Default Web Site), and then, in the action pane, click Properties.
On the Outlook Web Access Properties page, click the Private Computer File Access or Public Computer File Access tab.
Under WebReady Document Viewing, select the check box next to Enable WebReady Document Viewing to let users view common file types in Outlook Web Access.
To modify the types of files that you want users to be able to view in Outlook Web Access, click the Supported button under WebReady Document Viewing.
On the WebReady Document Viewing Settings page, select the default values, or delete one or more of the file types.
Click OK to save your changes.
The following example uses the Set-OwaVirtualDirectory cmdlet to prevent users on public computers from downloading files:
Set-OwaVirtualDirectory -identity "owa (Default Web Site)" -WebReadyDocumentViewingPublicComputersEnabled $false
For information about syntax and parameters, see Set-OwaVirtualDirectory.
