How to Add and Sync Microsoft Exchange Contacts for Your iPhone
You probably want all of your contacts in your new iPhone, but don't want to have to go through the process of creating new contacts in your phone. Don't worry – you can import them! Particularly in a corporate setting, some of your contacts, such as the company directory, may be in Microsoft Exchange.
As long as the technical support folks in your office will give you the access information, you can sync the contacts from Microsoft Exchange with your iPhone. Microsoft Exchange uses over the air (or OTA) syncing to import and exchange information between the Contacts app on your iPhone and the contact data stored in the Microsoft Exchange cloud.
Follow these steps to set up the account on your iPhone:
Tap Settings→Mail, Contacts, Calendars.
The Mail, Contacts, Calendars screen opens.
Do one of the following.
This has two quick steps:
If you set up a Microsoft Exchange account when you first set up your iPhone or when you set up e-mail, tap the name of that account in the list that appears.
Turn Contacts On with the toggle switch in the account screen.
This one is easy, too:
Tap Add Account to set up a new account.
Fill in the requested information.
After the information you entered is verified, you'll be asked to turn on a series of switches to establish which types of things you want to sync. Turn on Contacts. (Turn on the others such as Mail, Calendars, Bookmarks, or Notes if you want to sync those with Exchange.)
You now see Microsoft Exchange in the list of accounts on the Mail, Contacts, Calendars settings screen.
Tap the Save button in the upper right corner and you return to the Mail, Contacts, Calendars settings screen.
Tap Fetch New Data.
Tap Push On.
Anytime changes are made to the contacts on the server now associated with your Microsoft Exchange account, those changes are pushed to your iPhone.
If your server doesn't support push, or you want to conserve battery power, select a default fetch interval — every 15 or 30 minutes, or hourly.
Your iPhone contacts the server for new data at the interval you select.
