    Hi @Pham Tien Dung ,

    What is the error report? Are you having problems updating from CU20 to CU23? You need to update to Cumulative Update 23 for Exchange Server 2016 (KB5011155) first: https://www.microsoft.com/en-us/download/details.aspx?id=104132

    Then install the latest SU (SU update is cumulative and will include previous patches): https://support.microsoft.com/en-us/topic/description-of-the-security-update-for-microsoft-exchange-server-2019-2016-and-2013-march-14-2023-kb5024296-e13b0369-2102-4c95-bee2-456514630727
