On September 17, 2019 Microsoft released its quarterly updates for Exchange. This time, the updates contain Exchange 2019 Cumulative Update 3 and Exchange 2016 Cumulative Update 14. No updates are released for Exchange 2013 or Exchange 2010.
Over the past 20 years we’ve seen some dramatic changes in Microsoft Exchange Server. Exchange server 2000 was the first version that was using Active Directory, after switching from its own directory that was in Exchange server version 4.0 until version 5.5.

Many companies use old-style public folders, known as legacy public folders, on Exchange Server 2010. Often, the public folder hierarchical structures have grown uncontrollably for years. And not only in terms of data volume but also in the number of folders and the folder depth in the public folder hierarchy. For these reasons, many companies fear legacy public folder migration to modern public folders.
On February 12, 2019, Microsoft released its quarterly updates for Exchange server, and in this case Microsoft has released Exchange 2019 CU1, Exchange 2016 CU12, Exchange 2013 CU22 and Exchange 2010 SP3 Update Rollup 26 (although the latter is not really a quarterly update).
