    Good day @Thai Group,

    This error “Something went wrong [48v35]” usually appears when there is a temporary issue with the Office sign-in session, cached credentials, or the local Office installation.

    You can try the steps below:

    1. Sign out and sign back in to Office

    • Open any Office app (Word, Excel, etc.).
    • Go to File > Account.
    • Select Sign out, then close all Office apps.
    • Open the app again and sign in with your Microsoft account.

    2. Clear cached Office credentials

    1. Close all Office apps.
    2. Open Control Panel > Credential Manager.
    3. Select Windows Credentials.
    4. Remove entries related to MicrosoftOffice, Office, or ADAL.
    5. Restart the computer and sign in again.

    3. Repair the Office installation

    1. Go to Control Panel > Programs > Programs and Features.
    2. Find Microsoft 365 / Office in the list.
    3. Click Change.
    4. Run Quick Repair first. If the issue continues, try Online Repair.

    You may also want to try signing in at https://www.office.com to confirm that the account and subscription are working normally.

    If the issue continues, it would help if you could share:

    • Which Office product you are using (Microsoft 365, Office 2021, etc.)
    • Whether the error appears during installation, activation, or sign-in
    • A screenshot of the error message (please remove or blur any personal information)

    That will help the community narrow down the cause.

    Error code 2147942402 with the message “Something went wrong. An unexpected error occurred.” when working with Microsoft 365 / Office apps is a generic failure. Use the standard Office repair and reinstall steps that address this class of issues.

    Follow these steps in order:

    1. Restart the device
    • Close all Office apps.
    • Restart Windows.
    • Try the Microsoft 365 / Office app again.
    1. Run an Online Repair of Microsoft 365 / Office Online Repair is more thorough than Quick/Automatic repair and is the recommended fix for recurring “something went wrong” errors.

    On Windows 11/10:

    1. Close all Office apps.
    2. Open Settings → Apps → Apps & features.
    3. Find the Microsoft 365 / Office installation in the list.
    4. Select it, choose Modify (or Advanced options → Repair depending on the build).
    5. When prompted, choose Online Repair (full repair), then continue and let it complete.

    If using Control Panel:

    1. Open Control Panel → Programs → Programs and Features.
    2. Select the Microsoft 365 / Office product.
    3. Choose Change → select Online Repair → follow the prompts.
    4. If repair does not resolve the issue, reinstall using the offline installer Network, proxy, firewall, or antivirus interference can cause persistent “something went wrong” errors. In that case:
    5. Uninstall Microsoft 365 / Office from Settings → Apps → Apps & features or from Control Panel → Programs and Features.
    6. Reinstall using the Microsoft 365 offline installer as described in Use the Office offline installer. This bypasses many connectivity-related problems.

    If the problem persists after a full Online Repair and reinstall with the offline installer, collect the correlation ID, timestamp, and error details already provided and contact Microsoft support for deeper investigation.
