Do you need these mail server settings?

You can use the mail server settings in this article to manually set up your email app to send and receive email with an iCloud email account. However, you shouldn't need to do that if you meet iCloud system requirements and can use any of these setup methods:

  • Use iCloud Preferences on your Mac in OS X Lion 10.7.4 or later.
  • Use iCloud for Windows on your PC in Microsoft Windows with Outlook 2010 through Outlook 2016. Set up two-factor authentication and, if needed, generate an app-specific password* to use for iCloud Mail.
  • Use iCloud settings on your iPhone, iPad, or iPod touch with iOS 7 or later.
