Problem:

The User has created extra folders under their Contacts folder in outlook, but can't select the email addresses of people in the new folder when sending email.

Solution:

You can create folders with contacts in them, but they won't show up in the email address book list when you send an email.

You need to do the following:-

1. Go to your Contacts area in Outlook.
2. Right-click on the relevant contacts folder under 'My Contacts' and go to 'Properties'
3. In the box which appears, select the Outlook Address Book tab and put a tick in the 'Show this folder as an Email Address Book' checkbox.

This folder will now be accessible when selecting email addresses.
