The plug-in execution failed because the Sandbox Client encountered an error during initialization

Question

My Dynamics CRM instance refuses to run plugins. Unfortunately I don't have physical access to the environment, I cannot debug or investigate. Only guess and instruct system administrator to try another approach.

I started from compiling sample plugins from MS CRM SDK and registering it. On the server it's possible to register in sandbox mode only. I don't have Deployment Administrator privileges.

Plugin is registered on Create message on account entity — in the way SDK asks to do. But following run time error blocks execution:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: The plug-in execution failed because the Sandbox Client encountered an error during initialization.Detail:

• I tried different types of plugins, either custom or samples from Microsoft, all the same — they fail on remote server.
• I tried the same plugins on local development server — they all succeeded.
• I tried to run Sandbox service on local development server under minimal privileges to reproduce the error locally, but it doesn't show up.
• I asked to run Sandbox service on remote development server under maximum privileges to resolve issue remotely, but in vain.

Could you please give me an clue, what I could try next, to fix the issue?

Answer 1

I had a similar issue that I was able to resolve by running a repair installation of CRM and reconfiguring the service accounts that each service was set up as.
