RealAccount
RealAccount works by combining an Outlook mail folder with an options set. These are mainly focused on accounts handling, such as selecting an account and a signature. Once installed, RealAccount adds its own page to the Outlook folder properties pane. By default RealAccount is disabled, so nothing changes. To take advantage of it, setup your Outlook environment like the following:
Define your accounts by using standard Outlook dialogs in tools®email accounts. Define your signatures in tools®options®mail format®signature;
Disable the automatic signature insertion at tools®options®mail format®signature both for new and reply/forward emails (with Office Outlook 2003, you have to disable them for each defined account). Also, disable Word as editor: RealAccount works with the Outlook internal editor only ;
Define rules to move incoming emails to specific folder based on - say - account used, specific words in topic, etc. the same for outgoing emails.
Now, you are ready to define RealAccount behavior: use its tab on specific folder’s properties and define which account and which signature to use when composing new mail, reply, etc.
