When you install Cumulative Update 2 for Exchange Server 2016 on a Windows server that is running a Russian version of a supported operating system, SETUP fails and the MSExchangeTransport service won’t start.


This issue occurs because a product string translation into Russian exceeds allowable length. This causes an exception to occur during service startup.


To fix this issue, install Cumulative Update 3 for Exchange Server 2016 or a later cumulative update for Exchange Server 2016.


Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
