Anonymous2024-04-02T09:49:18.85+00:00 Hi@Abdulaziz ALHAKMANI, does this problem only occur in OWA? Does the same problem occur in Outlook client? It is recommended that you open the IIS Manager. Navigate to Server Name > Sites > OWA. Under the OWA application, ensure that Windows Authentication is enabled. If Basic Authentication is enabled, try disabling it as this may result in a prompt for a username and password.
