Before switching to the Outlook app, you should check to see if you have Contacts or Calendar items on your device and not in Microsoft 365.  

Contacts

1. Tap Settings
2. Tap Contacts
3. Tap Accounts
4. Tap Add Account
5. Tap Microsoft Exchange 
6. In the Email Address field, type your HawkID@uiowa.edu

10. Enter your HawkID password in the Password field

Calendar

Verify that any events you added to your calendar via your iPhone are on the correct calendar.  They should be on your Microsoft 365 calendar and not the iPhone calendar.   Otherwise, you won't see them when you use the calendar in Outlook.

Older iOS versions

The Outlook app is no longer available for download for versions older than the two most recent versions. To access your university email on your device, follow the instructions below to remove the account from the default mail app, then update your device to the most recent version, and follow the above instructions to set up Outlook mobile.  If you have an older iPhone, you may not be able to update to the latest iOS so you won't be able to use Outlook mobile.

Note: While older versions of Outlook already installed will still work on devices running older iOS versions, these devices will not get new app updates. Users can expect a degraded experience of the Outlook for iOS app over time if they do not stay up to date.  Microsoft only supports the two most recent OS release versions.

To remove your mail account from the default Mail app on iOS:

1. Tap Settings.
2. Tap Passwords & Accounts.
3. Tap your Microsoft 365 account
4. Tap Delete Account.
5. Choose which items (email, calendar, contacts, etc.) you want to delete (we recommend deleting all). This will delete all email, calendar, contacts, etc. from the device. Exception: If you have contacts stored locally on your device, do not remove contacts.
6. Tap Delete Account to confirm.
