This option controls which address book you see when you open the Address Book (via clicking Ctrl+Shift+B) and when you click the To, Cc, or Bcc buttons when composing e-mails.

In order to increase the speed of opening e-mail messages and reduce risks involved with opening of unsolicited messages, you can switch Outlook to the plain text reading mode.

Outlook uses two features to resolve and complete names entered into email messages: AutoComplete and Autoresolution.

Use Outlook rules to copy all incoming messages to the specified folder. E.g., copy all e-mails with OfficeToolTips tips subject to the OfficeToolTips folder.

By default, Outlook, displaying the note, shows the date and time of the last modification that was made to the note, but you can hide those time stamp.

Having notes of different colors can help you be more organized, and sometimes different-colored notes will help put a smile on your face.

Outlook can display either the number of unread e-mails or the total number of e-mails in a folder alongside the folder name.

This rule will be useful if you receive a lot of messages (for example, reports) from your colleagues and use rules to copy or move correspondence to the specific folders (like Rule to copy all correspondence about some subject to the specific folder or Rule to move all correspondence about some subject to the specific folder). Unfortunately those rules wouldn't work for messages with empty subject, but you still can create a rule to send an Auto-Reply if the message don't have a subject.

If you want to construct a more complicated distribution list, with some recipients on the To field, some recipients on the Cc field, and yet more recipients on the Bcc field, you have to use a message template where you explicitly assign recipients to each field.

Any of Outlook's default views can be modified to suit your needs. You can customize the fields displayed, sorting, grouping, filtering, fonts, and other formatting options.
