    Hi Sylvain, Welcome in Community

    According to reports from users on Microsoft’s official forums, the most common causes include:

    Temporary issues with Microsoft authentication servers

    Corrupted files in the credential cache

    Conflicts between personal and work accounts

    Problems with local user profiles or certificates

    Third-party software (such as antivirus tools) interfering with secure connections

    Here are some steps you can try to fix the issue:

    1. Clear stored credentials

    Press Win + S and type Credential Manager

    Open Windows Credentials

    Remove any entries related to MicrosoftOffice or MicrosoftAccount

    Restart your PC and try signing in again

    2. Repair Office apps

    • Go to Settings > Apps > Installed apps

    Search for Microsoft Office

    Click Modify, then choose Repair

    This process reinstalls missing or corrupted components that may prevent authentication or synchronization with your Microsoft account.

    Let me know how it goes

    The error details provided (correlation ID, DPTI, tag, code 2147483661, message “An unexpected error occurred”) indicate a generic, unexpected failure in the Microsoft 365/OneDrive sign-in or service flow. This type of error is not meant to be handled directly by users and does not map to a specific, documented error code in the provided references.

    For similar “An unexpected error occurred” or sign-in issues in Microsoft 365 apps on Windows or mobile, the following actions have resolved cases:

    1. If the error occurs in Outlook or Teams on a mobile device (for example, Samsung phone):
      • Uninstall Outlook and Teams from the device.
      • Restart the device.
      • Reinstall Outlook and Teams from the official app store.
      • Sign in again.
    2. If the error occurs in Microsoft 365 apps on Windows (Word, Outlook, etc.):
      • Run an Office Repair from Windows (Control Panel → Programs and Features → select Microsoft 365/Office → Change → choose Online Repair). Online Repair is more thorough than the automatic quick repair.
    3. If the error is tied to a temporary service or tenant issue (for example, similar to temporary login issues in Outlook/Teams):
      • Wait 30–60 minutes and try again, as some issues are transient and resolved by backend fixes.
    4. If the problem persists across devices and apps:
      • Contact Microsoft 365 support with the correlation ID, timestamp, and error code so support can look up the server-side logs associated with this failure.
