Outlook: Preventing Users from Adding Email Accounts to Outlook

How can I prevent users from adding home email accounts (e.g., MSN Hotmail, POP) or other email accounts to their Outlook profiles?

To prevent a user from adding an outside email account to an Outlook profile, create a DisableHTTP entry of type REG_DWORD in the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Options registry subkey and set the value to 1. Beginning with Microsoft Office XP Service Pack 2 (SP2), you can create registry entries to prevent users from adding POP, IMAP, Exchange, and other accounts to their profiles. You would need to create DisablePOP3, DisableIMAP, DisableExchange, and DisableOtherTypes REG_DWORD entries in the HKEY_CURRENT_USER\Software\Microsoft\Office\10.0\Outlook\Options subkey and set the value of each to 1 to disable the addition of any such account. Set the value to 0 to let users add such accounts. For more information about these changes, see the Microsoft article "OL2002: The Options to Prevent an Exchange, POP3, IMAP, and Other Server Types Accounts Are Not Available" (http://support.microsoft.com/
