You are a messaging professional. Your company uses a Microsoft Exchange Server 2003 messaging system. The company has five offices.

The company plans to upgrade all computers to Microsoft Exchange Server 2007 over the next 18
months. All the client computers use Microsoft Office Outlook 2003 configured in cached mode.

messaging system is enabled for each office.

computer was the first member of the administrators group. The computer retains the default
configuration.
