If you have Contacts in the Contacts folder but they are not accessible when you click on the To button, check these settings:
Make sure the Contact folder is enabled as an email address book. Right click the Contacts folder, choose Properties then Outlook Address Book.
Is the box to enable as email address book is checked ?
1. Go to Tools |
2. Email Accounts,
3. Choose View or change existing directories or address book.
Is the Outlook Address Book present ? If it isn't listed, add it and close and restart Outlook. If it is listed, then remove it and close then restart Outlook and
repeat these steps to add it.
Thanks I hope this will help you
