    Hi @Jitendra Mapari ,

    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
