AutoBCC 3.1

It automatically sends a blind-copy of all your outgoing messages to another address, for monitoring team communications with customers or just to improve workflow.
Once the add-in is installed, click on Tools > Options in Outlook's menu and select the AutoBCC tab in Outlook 2002 - 2007 (see below), or File > Options > Add Ins > Add Ins Options in Outlook 2010. There you can select CC or BCC and enter the destination e-mail address or Exchange mailbox name. Multiple addresses can be separated by semi-colons.
