Hi Tran_Hoa_Binh,

As I can see from the logs, this is a simple Encrypted Alert, which is one type of notification/indication for the closing of the SSL/TLS session. Usually, the sender/transmitter sends this alert once there is no data to transmit.

    Hi Tran_Hoa_Binh,

    Microsoft Remote Connectivity Analyzer is a great and comprehensive tool that we use to troubleshoot the numerous issues of the email servers, Microsoft Exchange on-prem, and Microsoft Exchange Online. 

    Please follow the below link for Microsoft Remote Connectivity Analyzer, and perform some tests by yourself, (some tests required the full detail of the mail server along with password).

    Hi Tran_Hoa_Binh,

    I've tested the SSL server endpoint through Microsoft Remote Connectivity Analyzer. I have verified the public certificate for validity, compatibility with Microsoft TLS 1.2, and cipher suite. However, it passed the test, the screenshots are attached.
