Accessing an attachment using Microsoft WebReady Document Viewing gives an error indicating that the document cannot be converted because it is larger than the maximum size limit. How can I change the size limit?

When a user clicks on the Open as Web Page link to view a supported file attachment which exceeds the default WebReady Document Viewing file size limit, Outlook Web Access will display the following error:
The document cannot be converted by the WebReady Document viewing service because it is larger than the maximum size limit set by the administrator for your organization.
To alter the WebReady Document Viewing file size limit,
  1. On the Client Access Server (CAS), open the registry editor (regedt32.exe)
  2. Navigate to HKEY_Local_Machine\System\CurrentControlSet\Services\MSExchange OWA
  3. Right-click on MSExchange OWA and create a new Key called WebReadyDocumentViewing
  4. Under WebReadyDocumentViewing , create a DWORD with value MaximumDocumentInputSize
  5. Set a value to the desired size e.g. 10240 kb = 10MB
  6. Under WebReadyDocumentViewing , create a DWORD with value MaximumDocumentOutputSize
  7. Set a value to the desired size e.g. 10240 kb =10MB
  8. Restart the World Wide Web Publishing Service for the changes to take effect
