Mail is an email and newsgroup client developed by Microsoft and included in the Windows Vista, 8, and 10 operating systems. The main feature of Mail is sending and receiving email. Windows Mail included fairly minimal changes to the application's user interface, but introduced major architectural changes when compared with its predecessor, Outlook Express, and is a fundamentally different application. The different versions do not share a common code base, but they share similar functionality. Like in Outlook and Outlook Express, Mail uses Control + E, not Control + F, to search.
