You can set up and sync Apple, Google, Microsoft, and many other accounts right to your iPhone or iPad!

Whether you use Apple's iCloud, Google's Gmail, Microsoft's Outlook or Exchange, or something else, it's easy to set up all your mail, contacts, and calendar accounts to sync to your iPhone or iPad. You can enable iCloud when you first set up your new iPhone or iPad, or enable any service at any time in Settings. Here's how!

How to set up iCloud mail, contacts, and calendars on your iPhone or iPad

  1. Launch the Settings app on your iPhone or iPad.
  2. Tap iCloud.
  3. Enter your iCloud email and password and tap Sign In.
  4. Turn On the services you want to sync with your iPhone or iPad. By default most, if not all, of iCloud's services are turned on.

    In Settings tap on iCloud, enter your login information and turn on the services to sync.

How to set up Gmail, Google Calendar, and Google Contacts on your iPhone or iPad

If you want to add your Google account to your iPhone or iPad's system apps, you'll want to go to Settings > Mail, Calendar, Contacts.

Under the hood, Apple is using the open standard IMAP, CalDAV, and CardDAV services to handle syncing Google services; unfortunately, Gmail retro-fitted support for IMAP, and it can be quirky at times—especially if you like Gmail's labeling system.

If you want to use the built-in iOS Mail app and its unified inbox, however, and you don't have a paid account, it's your only option.

  1. Launch the Settings app from your Home screen.
  2. Tap on Mail, Contacts, Calendars.
  3. Tap on Add Account.

    Launch settings, tap on Mail, Contacts, Calendars, and tap on Add Account.

  4. Tap on Gmail.

  5. Enter your login information for your Google account.
  6. Tap on Allow when prompted with the "iOS would like to..." screen.

    Tap on Gmail, enter your login info, and tap on allow,

  7. Tap on the Gmail button.

  8. Under the account heading you can choose which services you'd like to sync: Mail, Contacts, Calendars, or Notes by moving the corresponding slider to the right.
  9. Tap on Save.

    Tap on Gmail, choose which services to sync and tap on save.

After you save your account, you can access your settings at any time by tapping the Gmail entry under the Accounts header. If you'd like to change the description from "Gmail" to something more apt, tap the Account button, then tap the Description field.

You can also choose to run Google's services in Google's own iOS apps.

  11. Move the Calendars Slider to the right to sync your calendar's account with your device's.
  12. Tap on Save.

    Tap on next, adjust the calendars slider and tap on save.

Success! Your Gmail calendar will now sync with your Calendar app on your iPhone, so any existing or new events made in your Google account or on your iPhone will be visible and updated in both.

How to set up Outlook mail, calendar, contacts on your iPhone or iPad

And you're done! You will now get all of your mail from your Microsoft email service to your iPhone or iPad's unified mail inbox. You can also set up Outlook.com as an Exchange account.
