title: Execution order for Dynamics 365 plugin for same entity but with different messages
body: <p>Hi I need one suggestion
  For email entity I have 3 plugins, all of them are pre operation and sync
  3 plugins one for each create, update and send message
  All of them are having execution order 1
  Is it ok to have same execution order for same entity pre operations, even though the messages are different.
  Will there be any concurrency issue?</p>
