You can use command-line parameters to quick-start Microsoft Lync 2010. For example, if a user clicks a phone number in another application, the application can start an instance of Lync 2010 and initiate a call to that number.

Lync 2010 can also recognize a semicolon-delimited list of contact names for multiparty conferencing.

If Lync 2010 is configured to automatically sign in when started, then starting Lync 2010 with command-line parameters will open the Lync main window. If Lync is not configured to automatically sign in when started, the sign-in window opens.

The following table shows the available parameters.

Lync 2010 Command-Line Parameters

Extension Format of Data Action

If Lync 2010 is configured to use the Transport Layer Security (TLS) protocol, functions exactly like sip:. If TLS is not being used, displays a dialog box informing the user that a higher level of security is required.

If URI is self, instantiates the focus and brings up roster-only view. Otherwise, brings up roster view but does not send INVITE.

im:

SIP URI

Displays an instant messaging (IM)-only Conversation window with the SIP URI. Accepts multiple SIP URIs specified inside angle brackets (<>) without any separator.
