Creating custom menus in Outlook is a funny feature you can use to create groups of the options that you use most often, and then plug them into the menu you name and use yourself.

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.

In some situation you may want to send your vCard in every message. This lets recipients enter the information in their address book quickly and without errors.

By default, Outlook groups your emails by conversations. A conversation is a thread of messages with the same subject. However, if you need to find relevant notes somewhere in the last week's emails or an email from a particular person, navigating emails grouped by conversations takes a lot of time, and changing default grouping settings helps to locate the information much faster.

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.

Like the Inbox and other message views, the Calendar view also has a Reading Pane that lets you preview appointments and other items in your schedule without opening them.

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

vCard, also known as an electronic business card in Outlook, contains contact information similar to paper business cards. You can exchange electronic business cards in vCard format via MMS or instant messaging and send it as an email attachment. If you contact a lot of new people and want them to have your or another person's contact information, you can send your vCard in every email. This lets recipients enter the information in their address book quickly and without errors by importing your electronic business card from the attachment.
