Citrix Receiver displays the following security message when Office Communicator is started.

"Your virtual desktop is attempting to use your microphone or webcam..."

This message occurs when the microphone or webcam is not connected to the client.

Background

When using Microsoft Office Communicator or Microsoft Lync client within XenApp 6.5 environment and having clients run ICA Client 12.1 and later, this message is displayed when OCS is started in the published desktop. This message is displayed though the webcam or microphone is connected.

When starting a published desktop and automatically or manually starting the Office Communicator Client (or MS Lync client), this message is displayed by the Citrix Receiver (or ICA Client).

This issue was experienced with Citrix Receiver for Windows 3.3 and earlier.

This issue is resolved with the latest Receiver for Windows now available for download.
