Posting a form response to a Group Conversation/mailbox

I am trying to set up a GDPR compliant contact form on a site and have been considering the use of an embedded Office 365 form, combined with an Office 365 Group and associated mailbox open to external senders. The group is private and visible only to all our enquiry handler team. The contact form will simply ask for the enquirers email, name, subject and question. I would like Flow to then send this securely to the groups conversation/mailbox. We can then reply to the individual’s enquiry from within Outlook Online or Outlook Desktop - every member of the group having 'send as' permissions for the Group so responses are sent from the group's email address, and not their individual work emails.


I am aware that flow allows me to send a notification email upon receipt of a form submission, and that I can include any of the form's fields within this email. I could therefore send a similar email to the Group email address. However, I do not believe that would be GDPR compliant, given the issues with security of data transit over email.


What I envisage is Flow being able to achieve this securely through the Office 365 Group REST API. However, I don't know if an action exists that does this? It also seems silly, if such functionality is possible, to then be storing the form submissions within an Excel sheet. Is it therefore possible for Flow to delete the record after adding it to the Group mailbox/or simply tell Forms to stop storing a copy of responses in an Excel Spreadsheet (GDPR being all about how you store sensitive info)? I am aware there are other tools out there that are set up for enquiry handling. However, we only handle about 5 enquiries a week for a small project and it would be good if we can leverage the Office 365 tools we're paying for.
