Setup Office 365 on an iPhone

To setup Office 365 on an iPhone, you must have iOS software version 2.0 or higher and if you still have version 2.0 then its definitely time to upgrade –  its not 2008, you have bigger fish to fry!

Before beginning you need to be armed with 2 or 3 pieces of information:

  • Your email address – this will be something like
  • Your Password
  • And if you use AD Federation then there is a chance that your email and your AD account don’t match then you may have a user ID like ringo.starr@liverpool.local or LIVERPOOL\ringo.starr.

Office 365 login to Outlook Web App first

I like to test my account info using Outlook Web App first then I know that I have the information correct and I can rule that out as an issue if it doesn’t work first time – it’s very common for typos on the phone or password miscommunication to cause issues connecting.  Go to and test signing in with your credentials. If it signs in you now know you have the right information.

Setup Office 365 on an iPhone

  1. Turn on your iPhone, and then tap the Settings icon.
  2. On the Settings screen, tap Mail, Contacts, Calendars.
  3. On the Mail, Contacts, Calendars screen, tap Add Account.
  4. On the Add Account screen, tap Microsoft Exchange – you can have multiple Exchange accounts
  5. On the Exchange screen, tap the Email box, and then type your e-mail address. (For example
  6. Tap the Username box, and then type your e-mail address again unless you have been told it is different to the email, either because of Federation or some other company policy.
  7. Tap the Password box, and then type your password.
  8. Leave the Description box – by default, the Description box is filled automatically with your e-mail address. You can overwrite this if you want a different description. You can leave the domain box blank.
  9. Tap Next – the iPhone begins verifying the account information (this can take a minute or so) – if you receive a Verify Certificate message, tap Accept.
  10. The Server box should auto populate but if it doesn’t tap the Server box, and then type – do not include the https:// prefix.
  11. Tap Next.
  12. The iPhone sometimes begins verifying the new information. If you receive a Verify Certificate message here, tap Accept.
  13. Select the information you want to synchronize, and then tap Done – it is recommended to sync all items and use the Exchange repository as your central database for calendaring, contacts and email. Therefore if you change a contact in Outlook, your phone will be updated immediately and vice-versa.

Thats it. Done you now have Office 365 email setup on an iPhone.
