Copy fax number for all Exchange Contacts

What I need done: Search all the contacts of selected mailboxes on Exchange 2003 server, and copy the fax number of each contact from the fax property to the email-2 property with a little change. The change to the fax number should be like this: 1. Find if the contact has a fax number in the fax attribute. 2. get the fax number, and append a predefind DNS suffix to it. 3. Save the fax number with the predefined suffix on the Email-2 property of the contact. The code will search all the mailboxes that I will specify in a text file. The predefined suffix will also be specified in a another text file. Example: Old fax number on fax property: 9636363 New email-2 property: 9636363(at)[login to view URL] What I want: A vbscript or .Net Visual Basic application. Specific expertise that I am seeking: I need an experienced Outlook coder that have done similiar work. This should be a very easy job for someone with the required eperience. Good luck to all bidders. Guy
