Troubleshooting iOS and MacOS Devices

iOS / iPadOS Troubleshooting

The Apple iOS/iPhone Mail app may send you into a cycle of trying to sign in. If it will not accept your password several times, try this:

  • Have your iPhone / iPad running at iOS version 14 or higher
  • Go to Settings, and scroll down to 'Passwords & Accounts'
  • Select your UNK/UNL/UNO/UNOP email account and choose 'Delete Account' at the bottom
    • When it takes you back to the 'Passwords & Accounts' screen, choose 'Add Account'
    • Choose the 'Microsoft Exchange' option and fill in your email account information
    • When you get to the sign in page, sign in like you normally do and be sure to look for the notification from the DUO app to approve the log in.

MacOS Computer Troubleshooting

If you use Apple's Mail app on Mac desktops and laptops, you may experience a similar inability to sign back in. The fix is the same as on the iPhone/iPad: Remove your NU 'Exchange' account and add it back.

  • In Apple Mail, go to the menu item "Mail > Accounts...".
  • Select the "Exchange" account on the left, and click the minus sign '–' at bottom of the list to delete it.
  • To add the account back, select "Exchange" and enter your NU email address to sign in.
  • Look for the DUO notification on your DUO device to approve the login. Your email messages, calendar and contacts will re-download.

In October 2020, Microsoft will be making security changes which will remove support for Basic Authentication with SMTP. If you're not using Microsoft Outlook, check with the vendor of your email client on support for Microsoft's Modern Authentication (OAuth).
