Sometimes you would like to view two or more Outlook components at once, e.g. Inbox and Calendar or Tasks. Usually, whenever you click from one to another, the first is replaced in the same window. To view two or more Outlook components at the same time, open them in separate windows.
Example: To open your Calendar in a new window, right click My Calendar from the folder list and click Open in New Window. Your calendar will now automatically appear in its own window allowing you to easily move between your inbox and your calendar. This also works with the other components in Outlook such as the journal and tasks.
