You're most welcome. It seems that there is no issue with your password, firewall, and service provider's side. However, it might be a server configuration issue or caused by the port specification, and outlook is unable to detect it. It will be more transparent if you share a screenshot of the server configuration with the default port.

      Hi Tran_Hoa_Binh 

      I have the below suggestions:

      • Please check "Require logon using SPA (Secure Password Authentication)" for both incoming and outgoing
      • If not resolved from the above step, select Encryption method to "Auto"

      Outlook Configuration

        I have captured the packet, see the phenomenon that every time when have a pop-up, get Encrypted Alert.

        Thanks you.
