How can I disable multimedia file access for my OWA users?

In OWA 2000, users can download a Multimedia Control from the OWA Options page allowing them to insert audio and video content into messages. Some administrators may decide to disable access to multimedia files to prevent high use of server resources.

To disable the multimedia button in the OWA Options page, open the registry editor (regedit) and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWEB. Create a key named DisableMultimedia and set the value to 1. Care should always be taken when making edits in the system registry.
