Sync your iPhone with Exchange Server

1. To add an Exchange account to your iPhone, tap Settings, then Mail, Contacts, Calendars, then Add Account, then Microsoft Exchange. Note, you can configure only one Exchange account per device…


2. On the next screen, enter your complete email address, domain, username, password, and a description


3. Your iPhone will now try to locate your Exchange server using Microsoft's Autodiscovery service. If the server cannot be located, the screen to the right is shown. Enter your front-end Exchange server's complete address in the Server field.

Your iPhone will try to create a secure (SSL) connection to your Exchange server. If it cannot do this, it will try a non-SSL connection. To override the SSL setting, go into Settings, then Mail, Contacts, Calendars, select your Exchange account, tap Account Info, then toggle the Use SSL slider. 

Choose which type(s) of data you would like to synchronize: Mail, Contacts, and Calendars. Note that by default, only 3 days' worth of email is synchronized. To synchronize more, go into Settings, then Mail, Contacts, Calendars, select your Exchange account, and tap on Mail days to sync.
