The installation of the Exchange Server can change the Internet Information Services (IIS) configuration in a way that conflicts with Altium Concord Pro. To resolve this, the following changes must be made to the applicationHost.config file:

<handlers accessPolicy="Read, Script">

<add name="kerbauth" image="C:\Program Files\Microsoft\Exchange Server\V15\Bin\kerbauth.dll" preCondition="bitness64" />
<add name="WSMan" image="C:\Windows\system32\wsmsvc.dll" preCondition="bitness64" />
<add name="exppw" image="C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\auth\exppw.dll" preCondition="bitness64" />
<add name="cafe_exppw" image="C:\Program Files\Microsoft\Exchange Server\V15\FrontEnd\HttpProxy\bin\exppw.dll"  preCondition="bitness64" />
