I have a pretty standard workflow in my Dynamics CRM 2011, which sends email when new entity is created. Now, before email is sent, I'd like to attach some attachments by plugin.
Is it possible to capture some before-send event on email activity, so I could create plugin that before email is sent, do some check on created message, attach files and send it?
Edit:
Files fetched by web service from another system, they are not attachements of other entities in CRM.
