Clear AAD Broker Cache and Reconnect Your Work Account

This method resolves underlying authentication token mismatches by clearing corrupted credential caches and establishing a fresh connection to your organizational account.

Error 2148073494 often occurs when Windows retains outdated authentication tokens after a password change. Reinstalling Office does not remove these cached Windows credentials, which is why clearing the AAD Broker Plugin is necessary.

Sign out of all Microsoft Office applications

Open an Office app such as Word, click on your profile at the top right, select 'Sign out', and then completely close all running Office applications.

Clear the AAD Broker Plugin package contents

Open File Explorer and type '%LOCALAPPDATA%\Packages' in the address bar. Locate the folder named 'Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy', open it, and delete or rename its contents to clear the cached authentication data.

Disconnect stale accounts in Windows Settings

Press the Windows key + I to open Settings. Go to 'Accounts', click on 'Access work or school', locate your problematic work account, and click the 'Disconnect' button.

Reconnect your account and restart

In the same 'Access work or school' menu, click 'Connect' to add your work account back using your new password. Restart your Windows 11 computer and open Word to test the sign-in.

Organizational Access Warning: Use caution when disconnecting accounts, as this action temporarily removes your device from your organization's network and may briefly affect access to company resources.

Frequently Asked Questions

What does error code 2148073494 mean in Windows?

Error 2148073494 typically indicates a corrupted Trusted Platform Module (TPM) key or an authentication token mismatch within the Windows credential manager, frequently triggered after a password change for a Microsoft work or school account.

Why didn't reinstalling Office fix my sign-in error?

Reinstalling Office only replaces the application files. The sign-in error is caused by cached credentials and broker tokens stored deep within the Windows operating system, which remain on your device even after an Office application reinstall.

Will disconnecting my work account delete my personal files?

No. Disconnecting your work account from Windows Settings only severs the authentication link and device registration with your organization. Your local personal files and documents remain completely safe and untouched.

How can I prevent login issues if my personal and work accounts share the same email?

Using the same email for both personal and work Microsoft accounts often causes credential conflicts. It is highly recommended to add a new alias to your personal Microsoft account and make it the primary email to separate the two identities.
