as the subject, is there any way to allow Email "to" field able to easy copy and paste, drag and drop, just like the experience in outlook?
Hi,
It cannot be done unfortunately.
By design CRM use primary email field on the entity to send email.
If you haven’t set the primary email address field in Customer Engagement, you'll get the following error message.
“To track emails and perform synchronization, your Outlook email address should be the same as your email address in Microsoft Dynamics 365 apps.”
