We got a Service Account which we have configured to the run the below during set up
Application Service, Deployment Service, Async Processing Service and Monitoring Service
We got the same account created in CRM as an user which we came to know actually is not recommended so we wanted to Disable this.
When we tried to disable this user we got the error
Below the log downloaded
Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: The specified user is either disabled or is not a member of any business unit.Detail:<OrganizationServiceFault xmlns:i="www.w3.org/.../XMLSchema-instance" xmlns="schemas.microsoft.com/.../Contracts">

<InnerFault i:nil="true" />
<TraceText i:nil="true" />
</OrganizationServiceFault>
After this point who ever tries to access the CRM gets the same error
In order to make it work we had to
- Enable the Service Account by setting IsDisabled=0 in SystemUserBase from the back end
- Restart IIS
Would like to know if any body has come across this case and if there is a safest way to disable the service account in CRM.
Any suggestions would be of great help. Thank you.
