    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
