Set up Exchange ActiveSync on your iPhone, iPad, or iPod touch
When you add your Exchange ActiveSync account, you can sync your Mail, Contacts, Calendars, Reminders, and Notes wirelessly with your iOS device.
1. Add your Exchange account
Tap Settings > Accounts and Passwords > Add Account > Exchange.
2. Enter your address
Enter your email address. You can also enter an account description.
3. Connect to the Exchange Server
After you enter your email address, you can choose either Configure Manually or Sign In to connect to your Exchange Server.
If you select Configure Manually, you can set up an Exchange account with Basic authentication. Enter your email password. You might also be prompted to enter additional server information.
If you select Sign In, your email address is sent to Microsoft to discover your Exchange account information. If your account uses multi-factor authentication, you'll be guided through a custom authentication workflow. Learn more about Microsoft Modern Authentication.
If you need help, contact your Exchange Server administrator.
4. Sync your content
You can sync Mail, Contacts, Calendars, Reminders, and Notes. When you're finished, tap Save.
5. Edit your Exchange settings
Tap Settings > Accounts and Passwords, and select your Exchange account. You can also set up automatic out-of-office replies, and change how often you want Mail to sync. You can also tap your account name to change Advanced Settings like SSL and S/MIME.
