How to add multiple Exchange accounts to the iPhone 4

The iPhone Settings page

With the release of the iPhone 4 and iOS4, Apple has added support for multiple Exchange accounts on the devices that support the latest iPhone OS. This may not seem like a significant enhancement, but depending on how a person uses their iPhone, it could be a very welcome feature.

I use my iPhone with my work Exchange account as well as a number of IMAP accounts. At Westminster College, our IT department also uses a common account for many tasks, including software license management and support subscriptions so that employee turnover does not create gaps in service and support coverage. Beyond this need for a shared account, there are often other reasons why people need to sync multiple Exchange accounts (permanently or temporarily), which include:
  • An employee will be away for an extended period, so his duties are transferred to someone else during that time. This person may add both accounts to his iPhone.
  • An employee works in multiple departments and has multiple Exchange accounts.
  • A contractor works for multiple companies and has accounts with each one.

In this tutorial, I show how to add a second Exchange account to your iPhone; specifically, I add the aforementioned common support account that is shared among my IT staff. Note: This process will work on any iPhone that supports iOS4 -- the 3G, 3GS, and 4; original iPhone owners cannot run iOS4 and, therefore, won't be able to use these instructions.

This tutorial is also featured in a Smartphones blog post.

Steps for adding a second Exchange account
The first step to adding a second Exchange account is to go to the Settings page on your iPhone. On this page, tap the Mail, Contacts, Calendars option.
