Using iPhone's Mail App to set up Microsoft Exchange

General steps for setting up an email account on an iPhone

Important:

• ActiveSync Credentials Are Case-Sensitive.

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. Starting from iOS 18: Go to Settings > Apps > Mail > Mail Accounts > Add Account > Microsoft Exchange
   
   
    

2. For iOS 14/15/16/17: 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

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

4. Enter the full email address in the Email field and Description, then tap Next 

5. Click Sign in and enter the Password. If the server address can’t be determined, you will be asked to enter it.
   
   

   • Server name: your Exchange Proxy server name.
     Please email support@apptools.com.sg if you do not know the server name spelling

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

   • Username: type in the full email address or ActiveSync username (either one should work). If both options fail, we recommend using the format Domain\Username in the username field.
     Note: Exchange domain and Canonical username can be found under Exchange > ActiveSync. 

6. 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. 
   

   • 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.

7. 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.

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.
