Hi,
Greetings!
you mean to say that the recipients are not part of CRM and not any contact/account record and want to send email.
Generally the To look field look for the contact record to select the recipient. but there is a system setting, If the Email address of the recipient was not resolved’. Like in case you want to send out an email from D365 but you don’t have the same saved in the system as a Contact/account or any other record.
And it resulted in red cross like in TO field.
There’s a setting for this in Settings > Administration > System Settings, under Email tab.
You can simply flip the switch on ‘Allow messages with unresolved email recipients to be sent’ to Yes.
And, now enter the Email address in the Recipient (To) field and let the email go!
Is that you are referring??
As per Dynamics marketing email it will refer the To filed look up record.
