Dear Enzo ROZANSKI ,
Thank you for reaching out to the Microsoft Q&A Community. I understand you're having a frustrating problem with your deleted Microsoft account still being linked to Halo: The Master Chief Collection, preventing you from playing with your new, recovered account. I'm very happy to assist you with that.
The issue you're encountering, indicated by the error "he's still logged into my old account (which was deleted)" and the correlation ID*** PII Removed ***(Timestamp: 2025-07-30T13:39:54.977Z), means that Halo: MCC is trying to authenticate with outdated credentials stored on your PC. Even though you've successfully recovered and switched to a new Microsoft account, these old login tokens persist, causing the game to attempt to use an account that no longer exists.
Halo: The Master Chief Collection, especially on PC, relies heavily on your Windows and Xbox Network credentials. When you encounter this issue, it's typically because:
- Cached Credentials: Your computer, and potentially the game's launcher (like Steam) or the Xbox app, stores login information from your previous Microsoft account. These cached entries are instructing the game to use your old, deleted account for authentication.
Xbox Network Integration: Halo: MCC connects to the Xbox Network for all its online features, progression, and achievements. If the stored credentials are for a deleted account, the Xbox Network will deny access.
Security Protocols: Microsoft's security measures prevent access attempts from deleted or invalid accounts to protect user data, often resulting in login failures without a clear option to switch accounts directly within the game.
To resolve this, we need to systematically clear these outdated credentials from your system, forcing Halo: MCC to prompt you for a fresh sign-in with your current, valid Microsoft account.
Please follow these steps carefully to resolve the problem. Before you start, ensure you can successfully sign in to your new, recovered Microsoft account by visiting Microsoft account | Sign in or create your account today: Microsoft . Also, close Halo: The Master Chief Collection and any related Xbox applications (such as the Xbox app or Microsoft Store) before proceeding.
Step 1: Clear Web Browser Cache and Cookies in Steam (if playing on Steam)
If you play Halo: MCC through Steam, the integrated web browser it uses for sign-ins can hold onto old data.
Open Steam.
Go to Steam (top left menu) > Settings.
In the Settings window, select Web Browser.
Click Delete web browser cache, then OK.
Click Delete all browser cookies, then OK.
Close the Steam Settings window.
This step helps clear any persistent login tokens stored within Steam's internal browser, which might be used for Xbox Network authentication.
Step 2: Remove Cached Xbox Network Credentials from Windows Credential Manager
Windows securely stores login details for various applications, including Xbox Network. Removing these will prompt a fresh authentication.
Open Credential Manager:
Search for "Credential Manager" in the Windows search bar and open it.
Alternatively, press Windows Key + R, type control keymgr.dll, and press Enter.
Select Windows Credentials.
Scroll down to the Generic Credentials section.
Look for any entries that start with "Xbl" (e.g., Xbl|, Xbl_Ticket, Xbl|DeviceKey, or entries containing numbers like Xbl|1144039928).
For each "Xbl" entry you find:
Click on the entry to expand it.
Click Remove.
Confirm by clicking Yes or OK.
Close Credential Manager once all "Xbl" credentials are removed.
Step 3: Clear Halo: MCC's Local Web Cache Data
Open File Explorer.
In the address bar, paste %userprofile%\AppData\LocalLow\MCC\Saved\webcache and press Enter.
Delete all files and folders within this webcache folder. You can select everything (Ctrl + A) and press the Delete key.
Step 4: Launch Halo: The Master Chief Collection and Sign In
After clearing these cached credentials, the game should now prompt you for a new sign-in.
Launch Halo: The Master Chief Collection.
You should now see a fresh Xbox Network sign-in prompt.
Carefully enter the credentials for your new, recovered Microsoft account.
If prompted, allow the application to access your information to ensure full functionality.
Step 5: Verify Microsoft Store Account (if playing via Xbox App/Game Pass)
If you play MCC via the Xbox app or PC Game Pass, ensure your Microsoft Store account is correctly linked.
Launch the Xbox app.
Ensure you are signed in with your new, recovered Microsoft account (the one you use for Xbox).
Click on your gamerpic (profile picture) in the top left corner, then select Settings.
Under the Account section, select Change my Microsoft Store account.
Follow the on-screen instructions to sign in to the Microsoft Store with your new, correct Microsoft account. It's best practice for your Xbox profile and Microsoft Store account to be the same for seamless experiences.
Important Additional Guidance:
Restart Your PC: After completing all the above steps, it's highly recommended to restart your computer to ensure all changes take full effect and any remaining cached data is cleared from memory.
Account Security: Since your original account was compromised, please ensure your new Microsoft account is fully secured with a strong, unique password and Two-Factor Authentication (2FA) enabled for enhanced protection.
Contact Microsoft Support: If, after diligently following all these steps, you still face login issues, please contact Microsoft Support directly. Be prepared to provide the Correlation Id: *** PII Removed *** and Timestamp: 2025-07-30T13:39:54.977Z from your original error message, as this information is crucial for their diagnostics. You can initiate contact at Contact Us - Microsoft Support
I hope these steps help you resolve the problem and get you back into playing Halo: The Master Chief Collection with your correct account. If you require additional guidance or if the issue persists, feel free to reply to this thread, and I’ll be happy to assist you further.
