    Document whether the issue affects one user, multiple users, or multiple devices. Confirm exact error messages, recent changes (password reset, update, network change), and whether the same issue reproduces in web vs desktop workflows where applicable.

  2. 2

    Validate prerequisites and application/session state

    Info
    v

    Confirm the user is signed in with the correct corporate account, system time is accurate, network/VPN connectivity is stable, and the application is not running in offline or limited mode.

  3. 3

    Run safe diagnostics from the Commands section
