[HKEY_CURRENT_USER\Software\Microsoft\Tracing\uccp\ LiveMeeting]

"EnableFileTracing"= DWORD:00000001

"Tracing"= DWORD:00000001

Enables client-side logging, which maintains a detailed log in the %USERPROFILE%\tracing\ directory (filename LiveMeeting-uccp-*.log). Client-side logging supplements the default logging in the %TEMP% directory (filename pwconsole-debug*.txt).

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\ Outlook\Options\ConflictMsgCls

"IPM.Appointment.Live Meeting Request"= DWORD:00000004

Minimizes a conflict error that users of the Conferencing Add-in for Outlook may see when they are running the 2007 Microsoft Office System and Exchange Server 2007. In some circumstances, when the user creates or modifies a Live Meeting appointment, an erroneous Outlook message appears indicating that the appointment conflicts with another appointment.

1 The selected bit rate should account for transmission of both main and panorama video. Therefore, the value should be higher than the equivalent setting for Office Communicator. This setting applies to audio and video traffic. It does not apply to data traffic related to application sharing.

2 The default UDP/TCP port range is 1024-65535. By default none of these registry keys is set. Values in both the Attendee and Presenter modes must be set to make any of these settings become effective.

The registry keys listed in the following table are shared between the Office Live Meeting client and Office Communicator 2007 R2. When you install one client, these registry keys are created and provisioned for both clients. If a user changes his or her account information manually in one client, the account information changes in the other client.

Instead of requiring users to enter their account settings manually, administrators may want to configure these registry keys during client deployment. Otherwise, administrators need to provide instructions to users about how to enter account settings.
