Solution 1Recommended

Disconnect and Reconnect Your Work Account in Windows

Resetting your Windows account connection can force Microsoft Office to refresh its authentication token and resolve sign-in errors.

Open Windows Settings

Access Work or School

Click on 'Access work or school' from the left sidebar to view your connected organizational accounts.

Reconnect the Account

Test Office Activation

Account Page Issues: If the 'Access work or school' page freezes or does not load, you may be facing a Windows profile corruption and should contact your IT administrator.

Solution 2

Test Activation in a New Windows User Profile

Creating a fresh user profile bypasses any corrupted local system files that might be preventing your work account from loading or syncing properly.

Solution 3

Remove Duplicate Office Installations

Frequently Asked Questions

What does Office error code -2147023838 mean?

This error code typically indicates an authentication failure where Microsoft Office cannot communicate properly with the Azure Active Directory or Microsoft servers to validate your work or school license.

Why won't my Windows 'Access work or school' page load?

This issue is usually caused by corrupted Windows system files, restrictive group policies applied by your organization, or broken Windows account services. Running a system file checker or contacting your IT admin can help resolve this.

Can incorrect time settings cause Office activation failures?

Yes, if your computer's date, time, or timezone settings are out of sync with Microsoft's activation servers, the security certificates will fail to validate, leading to sign-in and activation errors.

Does running Office as an administrator fix sign-in errors?

In some cases, running the application as an administrator grants it the necessary permissions to update system registry keys related to licensing, which can push past basic activation blocks.
