For everyone who has Microsoft® Outlook® and doesn’t like the duplicate email addresses that popup when you select the “To:” (in the “Select Names” window), this add-in is for you.
It will change all fax numbers for a contact to have a pre-pended “Fax:” before the number. This has the effect of preventing Outlook from recognizing it as a valid address. This way, when you select “To:” and get the Select Names dialog box, you will see only one email address listed.
You can run this add-in against your default Contacts folder or against an Exchange public folder to keep everyone else from seeing the fax address listed as well. It works with any folder that has Outlook contacts contained within it including Business Contact Manager.
Plus, you can save time with this add-in because it will automatically convert any fax numbers of new contacts you create when you save those new contacts – without you having to do anything.
