I'm programming a VSTO in Outlook 2016 and I would like to enable/disable buttons in a Ribbon, based on the user's action of START A NEW MESSAGE or just OPEN/READ a message.

My problem is HOW detect when the user pressed NEW MAIL or just open a sent/received one message.

Could anyone help me? Thanks!

This tutorial actually deals with this exact scenario:

private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        inspectors = this.Application.Inspectors;
        inspectors.NewInspector +=
        new Microsoft.Office.Interop.Outlook.InspectorsEvents_NewInspectorEventHandler(Inspectors_NewInspector);
    }

Specifically, you attach to this.Appliaction.Inspectors. The tutorial takes the opportunity to modify the Subject and Body properties of the new MailItem:

void Inspectors_NewInspector(Microsoft.Office.Interop.Outlook.Inspector Inspector)
        {
            Outlook.MailItem mailItem = Inspector.CurrentItem as Outlook.MailItem;
            if (mailItem != null)
            {
                if (mailItem.EntryID == null)
                {
                    mailItem.Subject = "This text was added by using code";
                    mailItem.Body = "This text was added by using code";
                }

            }
        }
