First make sure that you are already in the new account - the one you are moving to. Under the Message menu Choose 'New Message' Under the View menu select 'Contacts Sidebar' You should see a list of all of your saved email addresses that you want to notify of the Change on the left - click on the top address. Under Edit Chose 'Select All" At the bottom of the Contacts Sidebar: click the button that says 'Add to Bcc:' Now that everyone is added to the BCC: Address line - Fill in the Subject, and a Message, and click send. Because everyone is sent to as BCC - no one will see any one else's address - for maximum privacy. (Put your address at the bottom of the addresses on a Bcc: line of its OWN to see for yourself how this looks when received.)

thanks it worked perfectly
