Microsoft Office has a feature that lets you send Outlook, Word, Excel, and PowerPoint files as Internet faxes. This feature relies on having the Windows Fax Printer Driver or Fax Services installed on the computer to send the faxes. If the Windows Fax feature is not enabled for your version of Windows, you can enable it.
In Control Panel, click Programs, and then click Programs and Features.
Note: In Classic view, double-click Programs and Features.
Click Turn Windows features on or off.
In the Windows Features dialog box, under Print and Document Services, select the Windows Fax and Scan check box.
