General steps for setting up an email account on an iPhone

Important: this article applies for Hosted Exchange email accounts. If you have Office 365 account, read the Microsoft Knowledge Base article here for instructions.

To set up an email account on your iPhone: 

  1. Enable ActiveSync on the mailbox.

  2. Find your particular settings (Username, Exchange domain, Server address).

  3. Add the Exchange account on your iPhone, following the instructions below.

Note: starting from iOS 11 devices do not support automatic setup for Hosted Exchange mailboxes. You will need to select Configure Manually when prompted.

Adding an Exchange account on the iOS device:

  1. For iOS 14: Go To Settings > Mail > Accounts > Add Account
    For iOS 12/13: Go To Settings > Passwords & Accounts > Add Account
    For iOS 11: Go To Settings > Accounts & Passwords > Add Account
    For iOS 10: Go to Settings > Mail > Account > Add Account

  2. On the Add Account screen, tap Microsoft Exchange.

  3. Enter the full email address in the Email field and your mailbox password in the Password field, then tap Next.

  4. The device will try to configure the Exchange server address automatically.
    If the server address can’t be determined, you will be asked to enter it.

    • Server name: your Exchange Proxy server name.

    • Domain: if your iPhone is on iOS 12 or higher, type in your Exchange domain as it's displayed on the ActiveSync page. If it's on iOS 11 or lower, leave it blank.

    • Username: specify the full email address

  5. The device offers to immediately sync with the Exchange server. If you choose not to sync at this time, you can turn on calendar and contact syncing later in Settings > Accounts & Passwords > Account, tap on your account.

    Changing sync settings

    • By default, Exchange ActiveSync pushes new data to your device as it arrives on the server. If you prefer to fetch new data on a schedule or to only pull new data manually, go to Settings > Fetch New Data to change the settings.

    • To change how many days worth of data is synced to your device, go to Settings > Mail > Account, select your account. The default setting is three days.

  6. To complete the setup process, tap Save and wait for the iPhone to test your incoming and outgoing mail settings and connect to your mailbox.

Please note that not all Exchange features are supported (for example, folder management, shared folders/calendars, public folders). Additionally, by default, the communication between the iOS device and Exchange Server is secure, using 128-bit SSL encryption and X.509 certificates.
