Live Meeting Registry Keys that are Shared with Office Communicator

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.
