Configure Exchange Online with the Outlook Mobile app on iOS and Android


Follow these instructions to configure your device if you have been migrated to Exchange Online.

Microsoft Exchange Online is a hosted messaging solution that delivers the capabilities of Microsoft Exchange Server as a cloud-based service, allowing you to access email, calendar, contacts, and tasks from your personal computer, the web, and mobile devices. Exchange Online integrates fully with Active Directory, enabling administrators to use group policies and other administration tools to manage its features across their environment. Though hosted by Microsoft, Exchange Online is still managed by the IU Exchange administrators and meets the same security and privacy guidelines as traditional, on-premises Exchange.

IU's Exchange Online environment does not support IMAP. For email configuration instructions, including details for those using Linux and Thunderbird, see Configure your email client for Exchange Online.
At this time, S/MIME is not supported in Outlook Mobile.


If you're preparing for Exchange Online before your migration and want to try changing your credentials, try switching to Depending on the client you are using, authentication may fail or you may get an error. If so, instead try ads\username or\username. You will then have to wait until after you've been migrated to update your username.

To set up your Exchange Online account in the Outlook Mobile app on your Android or iOS device:

  1. Open the Outlook app. If it is not already installed, download it from the Play Store (Android) or the App Store (iOS).
    If you already had your Exchange account set up and have been migrated to Exchange Online, select your circular account icon (upper left). In Outlook Mobile, tap the settings gear icon (lower left), select your Exchange account from the "Mail Accounts" section, and select Delete Account to remove your old account before proceeding.
  2. In Android, tap Add Account, enter your email address, and tap Continue. In iOS, in the "Add Account" screen, enter your email address, and then tap Add Account.
    If prompted for an account type, select Office 365. If prompted to select a personal account or a work or school account, select work or school account.
  3. At the prompt, enter your passphrase, and authenticate with Duo.
  4. At the "Add another account screen", if you would like to add another account, click Add and follow the prompts. Otherwise, click Maybe Later. Click through or skip the introductory information.
When you add an Exchange Online account to Outlook Mobile, it will show shared calendars that you may have added with other clients (such as OWA and Outlook for desktop) in the Calendars tab. To select/deselect specific calendars, tap the calendar icon, and then tap the person icon at the top left to view the calendar list. You can also add additional calendars to the list by clicking the + (plus sign) icon at the top left in the list view.
