Unable to set up Office 365 integration on Windows Server 2012 R2 Essentials

I’ve previously came across a problem with integrating the Windows Server Essentials 2012 Dashboard with Office 365. I’m posting the problem and solution here as it has helped some other users on a few forums.

Problem:

When running the Office 365 integration wizard in the Windows Server 2012 R2 Essentials dashboard the wizard runs for a very long time, and returns the following error:

“An unknown error occurred. Make sure that the computer is connected to the internet, and the try again. If you continue to to experience, restart the server and then try again”

My Solution:

After checking through the log files (C:\ProgramData\Microsoft\Windows Server\Logs\SharedServiceHost-EmailProviderServiceConfig.log) I found the following:

Microsoft.WindowsServerSolutions.O365Integration.O365ConfigureException: The remote server returned an error: (404) Not Found. —> System.Net.WebException: The remote server returned an error: (404) Not Found.
at System.Net.WebClient.DownloadFile(Uri address, String fileName)
at Microsoft.WindowsServerSolutions.O365Integration.SharePointManagementUtils.InstallCSOM()

I resolved the error by installing the ‘SharePoint Server 2013 Client Components SDK‘ which contains the CSOM modules. See here:

Once this had been installed the Integration wizard worked correctly.

Hope that this helps.
