I'm working with Dynamics CRM 2016, I want to send an Email from crm using an email address that the user insert (the email Id is taken from a field in incident-Entity
and not from crm-user) according to examples online the option is to use entityreference from another entity that will hold and get the Email address, is there a way not to use Entityreference but instead get my email address from a simple field on incident form?
Update:
but instead get my email address from a simple field on incident form?
This is not possible in CRM UI. But possible using the code snippet from the blog link in comment. You have to query the textbox content and put in recipient party address.
(These two lines are for sending email to activity party email Id from associated record non-email field from CRM UI, without any code or customization for this particular scenario)
Unfortunately you cannot achieve it.
Only way is associated record.
