Connecting iPad or iPhone to Exchange-Based Email

I love having the ability to connect multiple Exchange accounts to my iOS devices. From a testing standpoint, it's critical that I can diagnose email issues in a short amount of time. While I can create multiple profiles in Outlook to test accounts, I'd rather use one of my mobile devices to check calendar and email sync. I am rarely sitting at my desk and prefer to diagnose issues on the move.

I included the Apple instructions for connecting an iOS device to an Exchange account. You can add as many Exchange accounts as you wish.


From http://support.apple.com/kb/ht2480

1. To add an Exchange account to your iOS device, tap Settings > Mail, Contacts, Calendars > Add Account > Microsoft Exchange.
2. On the next screen, enter your complete email address, domain, username, password, and a description (which may be anything you like). Ask your Exchange Server administrator if you are unsure of the domain. If you are unable to view your folder list, or are unable to send or receive email, leave the domain field blank.
   
3. Your iOS device will now try to locate your Exchange Server using Microsoft's Autodiscovery service. If it cannot locate the server, you will see the screen below. Enter your front-end Exchange Server's complete address in the Server field. Contact your Exchange Server administrator if you are unsure of the address.
   
   Your iOS device 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 > Mail, Contacts, Calendars, select your Exchange account, tap Account Info, then toggle the Use SSL slider.
   After successfully making a connection to the Exchange Server, you may be prompted to change your device passcode to match whatever policies may have been set on your server.
   
4. Choose which type or types of data you would like to synchronize: Mail, Contacts, and Calendars. Note that by default, only three 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.
   Note that after configuring an Exchange ActiveSync account, all existing contact and calendar information on the iOS device is overwritten. Additionally, iTunes no longer syncs contacts and calendars with your desktop computer. You can still sync your iOS device wirelessly with MobileMe services.
