    Hi Jolayne Boynton

    I understand that New Outlook for Windows is asking you to sign in and then shows the error INTERACTIONREQUIRED. Could you confirm:

    • Is the affected account Outlook.com/Hotmail/Live, Gmail/Yahoo/iCloud, or an internet-provider email account?
    • Can you sign in successfully through a browser?
    • Does the same error appear after Repair and Reset?

    Meanwhile, try the steps below:

    1) Check whether the account works in a browser

    First, try signing in to your Microsoft account in a browser. If you cannot sign in there either, use Microsoft’s Sign-in Helper first: I can't sign in to my Microsoft account | Microsoft Support

    If browser sign-in works, continue with the steps below.

    2) Fully close New Outlook

    Close New Outlook completely by using Task Manager:

    • Right-click Start.
    • Select Task Manager.
    • Select Microsoft Outlook.
    • Select End task.
    • Reopen New Outlook.

    3) Repair New Outlook

    Go to: Windows Settings > Apps > Installed apps > Outlook (new) > Advanced options > Repair. After the repair finishes, open New Outlook again and try signing in. See: Repair apps and programs in Windows | Microsoft Support

    4) Reset New Outlook if Repair does not work

    If Repair does not fix the issue, go back to: Windows Settings > Apps > Installed apps > Outlook (new) > Advanced options > Reset. After resetting, you may need to add the account again.

    5) Remove and add the account again

    In New Outlook, go to: Settings > Accounts > Your accounts

    Then:

    • Select the affected account, if it appears.
    • Remove it from Outlook.
    • Add the account again.
    • Follow the sign-in prompts.

    6) If this is Gmail, Yahoo, AOL, iCloud, or an internet-provider mailbox

    Sign in to that provider’s webmail first to confirm the account and password still work. If the provider requires an app password, create one from the provider’s security page and use it when adding the account to Outlook. Some accounts may need an app password when being added to Outlook.

    7) Reinstall New Outlook if the sign-in loop continues

    If the same sign-in error continues after Repair, Reset, and re-adding the account, uninstall and reinstall New Outlook.

    • Open the Start menu.
    • Find Outlook (new).
    • Select Uninstall.
    • Reinstall New Outlook from the Microsoft Store.
    • Add the account again.

    Please tell me how it goes. If the problem persists, please don’t hesitate to reply to this thread and I will be happy to help. Have a lovely day!
