Hi Gaston NDOUMBE ,

Do the following:
1.Start IIS Manager on the server.
2.Navigate to Exchange Backend website > ECP Virtual directory.
3.Select Application settings > BinsearchFolder.
4.Check the paths to the Exchange directories that are listed. You might see directory paths that resemble the following:
•%ExchangeInstallDir%bin;%ExchangeInstallDir%bin\CmdletExtensionAgents;%ExchangeInstallDir%ClientAccess\Owa\bin
1.Replace the paths with the following paths:
•C:\Program Files\Microsoft\Exchange Server\V15\bin;
•C:\Program Files\Microsoft\Exchange Server\V15\bin\CmdletExtensionAgents;
•C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\Owa\bin

Option 2:
.\UpdateCas.ps1
.\UpdateConfigFiles.ps1
