Problem

You need to install KEA on a host running MS Exhange 2013, 2016, 2019 server, and ensure compatibilty.

Solution

1. Add the following values into registry (should be done with "Local System" rights):

   [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\KasperskyLab\SOYUZ\4.0\Environment] "EnablePorts"=dword:00000001 "EnableSignatureLevel"=dword:00000001 "ServerProfile"=dword:0000000a

2. In KEA policy, add the following telemetry exclusions:

    We highly recommend NOT to exclude UmWorkerProcess.exe.
