Active Exchange Server 2019 and 2016 systems receive consistent support from Microsoft developers in the form of timely cumulative updates. These updates are not arbitrary modifications; rather, they are purposeful responses to user queries and issues reported to the support team during that specific timeframe.
Each cumulative update represents a comprehensive Exchange setup that incorporates all the changes from previous Cumulative Updates (CUs). If your server has not received updates for an extended period, it is advisable to bypass installing all the previous updates and instead download and install the latest Cumulative Update exclusively. Neglecting regular Exchange updates can lead to consistency-related issues, resulting in errors such as “Exchange Database Consistency Check Failed” and others.
Once you’ve upgraded to a newer version of Exchange, it’s important to note that reverting to a previous Cumulative Update (CU) isn’t possible through uninstallation. Uninstalling the updated version will completely remove Exchange from the server, preventing a rollback to an older CU.
The Exchange operates on a quarterly release schedule, providing Cumulative Updates (CUs) that address customer complaints while occasionally introducing new features and capabilities.
Critical product upgrades encompass those addressing security bulletins from Microsoft or incorporating alterations to time zone definitions. During Mainstream Support, substantial product upgrades are provided monthly, as required, for both the latest Cumulative Update (CU) and the preceding CU. In Extended Support, critical product updates for the most current CU are issued on a monthly basis as necessary.
