Open New Outlook Message from C#

I am looking to generate an Outlook message from within my program, I am able to build and send from within the program or build and save, what I would like is to build then display to allow the user to manually select recipients from the AD listings... The code below is a mixup of samples here and other tutorial sites however none I can find just build then "display" the email without saving a draft or sending it from within the program...

also I am looking to find a way i can create a UNC link inside of an email IE: write out a path to the users folder \\unc\path\%USERNAME% or the likes

private void sendEmailOutlook(string savedLocation, string packageName)
    {
        try
        {
            Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
            Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

            oMsg.HTMLBody = "Attached is the required setup files for your <i><b>soemthing</i></b> deployment package.";
            oMsg.HTMLBody += "\nPlease save this file to your network user folder located.<br /><br/>\\\\UNC\\data\\users\\%USER%\\";
            oMsg.HTMLBody += "\nOnce saved please boot your Virtual machine, locate and execute the file at <br /> <br />\\\\UNC\\users\\%USER%\\";

            int pos = (int)oMsg.Body.Length +1;
            int attachType = (int)Microsoft.Office.Interop.Outlook.OlAttachmentType.olByValue;

            Microsoft.Office.Interop.Outlook.Attachment oAttach = oMsg.Attachments.Add(savedLocation, attachType, pos, packageName);

            oMsg.Subject = "something deployment package instructions";
            oMsg.Save();

        }
        catch(Exception ex)
        {
            Console.WriteLine("Email Failed", ex.Message);
        }

Microsoft.Office.Interop.Outlook.Application oApp = new Microsoft.Office.Interop.Outlook.Application();
Microsoft.Office.Interop.Outlook.MailItem oMsg = (Microsoft.Office.Interop.Outlook.MailItem)oApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

oMsg.Subject = "something deployment package instructions";
oMsg.BodyFormat = OlBodyFormat.olFormatHTML;
oMsg.HTMLBody = //Here comes your body;
oMsg.Display(false); //In order to display it in modal inspector change the argument to true

Regarding the link to the folder you should be able to use(in case that you know User Name):

<a href="C:\Users\*UserName*">Link</a>

A lot of companies have their employees user names attached to address entries (looks something like "John Doe(Jdoe)" where Jdoe is a username). when your user select a recipients or tries to send the email you could catch those event, and do something like

foreach (Outlook.Recipient r in oMsg.Recipients)
{
    string username = getUserName(r.Name);//  or r.AddressEntry.Name instead of r.Name
    oMsg.HTMLBody += "<a href='C:\\Users\\" + username  + "'>Link</a>"
}
oMsg.Save();
oMsg.Send();

where getUserName() is a method that extracts only the userName (Could use substring or RegEx).
