Appendix D: Registry Keys Shared with Microsoft Office Communicator

  • Article

Microsoft Office Communications Server 2007 and Microsoft Office Communications Server 2007 R2 will reach end of support on January 9, 2018. To stay supported, you will need to upgrade. For more information, see Resources to help you upgrade your Office 2007 servers and clients.

The registry keys listed in Table 4 are shared between the Microsoft Office Live Meeting client and Microsoft Office Communicator. 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 will change 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 will need to provide instructions to users about how to enter account settings.
