How to Set Up Corporate E-mail on Your iPhone

By Edward C. Baig, Bob LeVitus

The iPhone is friendly for business users, in large measure because it makes nice with the Microsoft Exchange servers that are a staple in large enterprises.

What’s more, if your company supports something known as Microsoft Exchange ActiveSync, you can exploit push e-mail (messages are pushed to your iPhone automatically as opposed to being pulled in on a schedule) so that messages arrive pronto on the iPhone, just as they do on your other computers. (To keep everything up-to-date, the iPhone also supports push calendars and push contacts.)

For push to work, your company must be simpatico with one of the last several iterations of Microsoft Exchange ActiveSync. Ask your company’s IT or tech department if you run into an issue.

Setting up Exchange e-mail isn’t particularly taxing, and the iPhone connects to Exchange right out of the box. However, you still might have to consult your employer’s techie types for certain settings.

Start out by tapping the Microsoft Exchange button on the Add Account screen. Fill in what you can: your e-mail address, username (usually as domainuser), and password. Or call on your IT staff for assistance.

On the next screen, enter the server address, assuming that the Microsoft Autodiscovery service didn’t already find it. That address usually begins with


The company you work for doesn’t want just anyone to have access to your e-mail — heaven forbid if your phone is lost or stolen. So your bosses may insist that you change the passcode lock inside Settings on the phone. (The passcode is different from the password for your e-mail account.) Now if your iPhone ends up in the wrong hands, your company can remotely wipe the contents clean.

After your corporate account is fully configured, you have to choose which information you want to synchronize through Exchange. You can choose Mail, Contacts, and Calendars by tapping each one. After you select an item, you see the blue On button next to it.


By default, the iPhone keeps e-mail synchronized for three days. To sync for a longer period, head to Settings and tap Mail, Contacts, Calendars, and then tap the Mail account that is using ActiveSync. Tap Mail Days to Sync, and then tap No Limit or choose another time frame (1 day, 1 week, 2 weeks, or 1 month).

If you’re moonlighting at a second job, you can configure more than one Exchange ActiveSync account on your iPhone; there used to be a limit of just one such account per phone.
