Settings in Outlook 365
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.
The Navigation Bar at the bottom of the Navigation Pane in Outlook includes the buttons for switching to Mail, Calendar, Contacts, Tasks, Notes, Folders, and Shortcuts views. By default, Microsoft Outlook displays Mail, Calendar, People, and Tasks text buttons, and you need the ellipsis button for other options. However, you can switch from texts to icons, remove and reorder buttons on the Navigation Bar.
By default, Outlook shows document tooltips (or screentips) when you hover on a button, but this option can be turned off.
AutoArchive in Outlook moves old items to a local archive data file to reduce the size of your mailbox. Global AutoArchive settings apply to the entire account, but you can define a more precise policy for some folders.
Usually, Outlook users use folders to organize messages, but you can also use colors, fonts, and styles. For example, you can assign a unique color to all messages from a particular person, e.g., your boss. Now, you can easily spot the emails from that person in your inbox and other mail folders.
Outlook displays only a small subset of the available fields for messages in the Inbox and other Mail folders. The default view for the Inbox is Compact, and this view does not display any columns. You can view multiple columns in the List view and add columns, such as Cc or Sensitivity, that show additional information.
