To organize your Outlook messages, you can create different Rules, but sometimes you don't want or can't create a rule for some messages because of “human factor”. E.g., some of your colleagues or friends doesn't use the correct words in the subject, doesn't use the agreed rules for messages.

Search Folders let you to access the information in your mailbox more quickly, because, unlike the ordinal folders, they do not dictate that message should belong to a single folder.

Outlook, like other Office applications, supports AutoCorrect - a feature that allows Outlook to correct common spelling and typing errors and to replace characters with symbols. You also can use AutoCorrect as a shortcut, which means you can type a small string of characters and have those characters replaced by a longer string.

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