CRM Workflow Paused: Cannot update parties unless email is in draft status

Hi All,

I badly needed help right now, there's a workflow that will send email to a CRM user and then create a task to a specific user after the task has been marked as completed. The problem is that the email is not sending and remains on Draft status and got this error:

Workflow paused due to error: Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: Cannot update parties unless email is in draft status.Detail:

I have to resume it manually to continue the WF.

Thank you very much!
