I have created a plugin with message as send (Post condition), setEntity(Post condition) and SetStateDynamicEntity(Pre-condition) with primary entity as Email. When user send an email with or without attachment, i am reading the ActualEnd date from the email entity then check null and update in the opportunity custom field as Last activity. It working fine in Non-prod environment, when we go for production it was not working.  When i tried to send the email when the server load increases or CRM server when slow, is there any possibility for plugin to get triggered before the ActualEnd field value get loaded in the email entity.
