The app makes entering email addresses quicker and easier by displaying contacts from both your phone's contact list and your server contacts list as you type. To use this feature:
1.Start typing an email address or name in the To:, CC:, or BCC: field of the message you're composing. The Composer will automatically prompt a list of possible contacts from your phone’s Contacts list.
2.Tap your desired Recipient, and it will be placed in the recipient field.
Note: Any new email address in the To:, CC:, and BCC will automatically be saved for future recipient suggestions.
