You can configure Outlook to open with a single window.

Microsoft Outlook is one of the most popular desktop email clients among Windows users. In Outlook, you can work with several types of data at the same time, including mailboxes, contacts and calendars. You may notice that each of these tools opens a separate Outlook window. If you do not want this to happen, you can configure Outlook so that it only opens a single window when it launches.


Step 1

Close all of the Outlook windows that are currently open by clicking on the red "X" symbol in the upper-right corner of each. Do not use the "Exit" command in the "File" menu.
