How to Fix Microsoft Teams Login Error 0x80048823 (January 2026)

​Are you being locked out of Microsoft Teams with the error code 0x80048823? Since the January 2026 security patch, thousands of business and student accounts in the US and UK are reporting this "Incorrect Timestamp" or "Authentication Failed" message. If you are stuck in a login loop today, January 24, 2026, here is the verified fix to get your Teams back online immediately.

​What is Microsoft Teams Error 0x80048823?

​The 0x80048823 error is a specific authentication glitch that occurs when there is a mismatch between your local device's security tokens and Microsoft’s Entra ID (formerly Azure AD) servers. In many cases, it is triggered by an incorrect time zone setting or a corrupted "AAD Broker" plugin file after a Windows update. This is specifically affecting Tier 1 enterprise users this week.

​4 Quick Fixes for Teams Login Issues

​Follow these steps in order to resolve the 0x80048823 block:

  1. ​Sync Your System Clock: This is the #1 cause. Even a 30-second difference can block your login. Go to Settings > Time & Language > Date & Time. Click "Sync now" under "Synchronize your clock." Ensure your Time Zone is set correctly.
  2. ​Delete AAD Broker Plugin Folders: Close all Office apps. Open File Explorer and paste this path: %localappdata%\Packages\Microsoft.AAD.BrokerPlugin_cw5n1h2txyewy Delete all files and folders in this location. This forces Teams to generate a fresh, non-corrupted security token.
  3. ​Clear Teams Cache: Navigate to %appdata%\Microsoft\Teams and delete everything. Restart Teams. This is a classic fix that resolves 90% of login "Timeout" errors.
  4. ​Disconnect Work or School Account: Go to Windows Settings > Accounts > Access work or school. Find your account, click Disconnect, and then click Connect to re-enroll your device. This refreshes your organization's security policy.

​Official Microsoft Status

​Microsoft Support has acknowledged that "identity validation inconsistencies" are impacting certain Microsoft 365 applications in January 2026. While they work on a permanent fix, the AAD Broker reset method is the only way for users in the US and UK to bypass the 0x80048823 error loop today.
