Some users want to make their personal contact list the default list instead of the Exchange domain list. This is done through Outlook Client.
1. Click the Tools menu (Outlook 2007) or the Home menu (Outlook 2010 / 2013 / 2016) and then click Address Book to open the address book.
2. In the address book, click the Tools menu and then click Options to load the addressing options.
3. For Outlook 2007, click the drop-down arrow next to Show this address list first. For Outlook 2010 / 2013 / 2016, select Start with contact folders or select Custom and rearrange the order of contacts as required.
4. Use the pull-down menu to select the contact list that you want displayed as the default when the address book is opened.
5. Click OK.
