Users randomly signed out due to token corruption after password change or session revoke

This issue is related to Microsoft Entra ID (formerly Azure Active Directory) — account object/token-state corruption suspected.

Hi team,

We are facing an issue with ~8 accounts where users keep getting signed out from Microsoft 365 apps (Teams, Outlook, OneDrive, etc.) on all devices (Windows, iOS, and even InPrivate browser sessions).

Symptoms:

• Error codes: 50133 / 50173 (session not valid due to password change / revoked grant expired).

Even after successful MFA authentication, sessions get terminated shortly after.

Occurs on both compliant corporate devices (Intune-managed) and personal devices.

Troubleshooting done:

Revoked refresh tokens via PowerShell (Revoke-AzureADUserAllRefreshToken).

Disabled and re-enabled MFA methods.

Wiped and re-registered authenticator app.

Cleared cached credentials (Windows Credential Manager, Teams cache, etc.).

Tested on brand-new devices → same issue persists.

Conditional Access reviewed: policies not blocking, MFA strength satisfied.

Observation:

The problem seems linked to account object / token-state corruption in Entra ID.

Affected accounts cannot maintain a stable session, while unaffected accounts in the same tenant work fine.

Workaround: using Microsoft Edge InPrivate window allows temporary access, but apps (Teams/Outlook) still force sign-out later.

Request:

Is this a known issue with Entra ID / token refresh?

What is the recommended escalation path if account object corruption is suspected?

Should we request Microsoft Support to perform a backend reset/reseed of the affected users’ security keys/tokens?

Thanks in advance for any guidance.Hi team,
