Hi Rahul,
Please add a new field, set is default value using following formula, then you can get all user accounts in this field. Publish the form to SharePoint form library
and don’t forget to add the field as a SharePoint column when publish the form.
eval(eval(Person, 'concat(pc:AccountId, ";")'), "..")
(Note: Please replace Person by inserting the pc:Person group field and pc:AccountID is the pc:AccountID field under pc:Person group)
So we can get the accounts in a list column, send emails using workflow using this field.
Best regards.
