Unable to Launch Exchange Admin Console/Shell - Could not load file or assembly 'Microsoft.Exchange.Net, Version=; Exception from HRESULT: 0x800705AF

Written by

Recently when I was installing and configuring Exchange Server 2016 on a LAB infrastructure to test some configuration, I encountered the following error,

Could not load file or assembly 'Microsoft.Exchange.Net, Version=, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The paging file is too small for this operation to complete. (Exception from HRESULT: 0x800705AF)

EAC .Net Error

Initially I thought, it was due to the resources of the server, where as it turned out to be in complete installation of pre-requisites for Exchange Server 2016. I did not bother to follow any document, instead I did it my own thinking that all steps are complete.


I was able to fix the issue by following the instruction below,

Step 1: Add the server feature Microsoft Media Foundation, by running the below command.

Install-WindowsFeature server-media-foundation

Step 2: Install the .NET Framework 4.5.2 if you missed during the pre-requisite preparation.

.NET Framework 4.5.2:Download

If you have already installed .NET Framework 4.5.2, try to repair and restart the server. It would solve the issue and you will be able to launch EMS and EAC easily.
