Microsoft Lync Controls depend on Microsoft Lync 2010 for presence and contact information. At any moment Lync 2010 may be in a number of different states. For example Lync 2010 may be signed in or signed out, or unable to connect to the WAN or the presence server. All of these states affect Lync Controls. This topic describes how each control responds to the different states.

Lync Controls do not show state errors and other error notices, these appear in the Lync 2010 user interface.

The phrase branch office resiliencyrefers to the ability of Lync Controls to handle connectivity failures. Lync Controls enter branch office resiliency mode when full connectivity to Microsoft Lync Server 2010, the WAN, or the datacenter is not available.

The term disableddescribes a control's state when Lync 2010 is not running. For example, in a PresenceIndicator control the contact name changes to "Unknown Contact", and a contact card is not displayed.
