Dear LO YU HONG,

Thank you for providing the error details.

Since this is a school (education) account, the account is managed by your school's IT department. The error "INTERACTIONREQUIRED" may indicate that additional authentication, sign-in requirements, or account-related actions are needed before access can be granted.

As this is a public community forum, I do not have access to your school's Microsoft 365 tenant, user accounts, or authentication settings, so I cannot investigate or modify the account on your behalf.

First of all, here are some troubleshooting steps I recommend you try:

Step 1: Sign out of the affected school account in New Outlook and then sign back in.

Step 2: Remove the account from New Outlook and add it again.

Step 3: Force Office to re-ask for credentials by doing this: Open Windows Settings > Accounts >Access work or school > Disconnect your school account > restart the computer and connect again

Step 4: Open Outlook on the web and check whether you can sign in there.

Note: If your school uses Microsoft Authenticator, ensure the app is installed, up to date, and that you can receive approval notifications.

However, if the issue persists, I recommend reaching out to your school's IT administrator or help desk. Your school's IT administrator can review the sign-in logs and authentication settings for the account and determine what is preventing the sign-in. For reference: How do I find my Microsoft 365 admin?

For more information, your school IT Admin can refer to this: What are Microsoft Entra sign-in logs? and Manage user authentication methods for Microsoft Entra multifactor authentication

Thank you for your patience and understanding. If you have any questions or get stuck on any steps, please feel free to reach out. Looking forward to your update.
