Actual Contacts for Outlook(ACO) is a Microsoft Outlook add-in for updating your address book and monitoring validity of e-mail addresses in the contacts. Select the contacts you wish to update and ACO will send them a message containing a form to fill. The respondents will be able to update their data in your address book by filling out the form. This program is also able to check your address-book. It takes it a few minutes to inform you about the contacts that contain invalid email addresses. The add-in also supports validation of the recipient list in Mail Merge Mode in Microsoft Outlook and Microsoft Word (a mail merge function is prerequisite for version 2002 or later ones). In order to check an address, ACO imitates sending a message to this address. When the server confirms or doesn''t confirm the existence of this address, the program cancels message sending and finishes the session correctly. So, address verification is technically correct and cannot be noticed by the address owner. Now Actual Contacts has the full functionality of Contacts Verifier which was earlier offered as a separate solution. Tasks that can be solved with ACO: 1) Updating your contacts. This is the main purpose of the program. To do it, just specify parameters and send the update request. 2) Collecting additional information. It often happens that new contacts are acquired during after exhibitions and seminars where you may only have managed to note their names and e-mail addresses. ACO will help you to collect the missing information quite easily! 3) Simple surveys. Customizable templates (with different fields included in the form) make the program a simple to use information tool. 4) Updating your contact information in your respondents'' address books. You can add information about yourself in the VCard format to your update request. Almost all e-mail clients and mobile devices can import this information into their contact lists.
