I ran into same issue while accessing sender email address for outlook mail item. To avoid 'security alert' do not create new Application object, instead use Globals.ThisAddIn.Application to create new mailitem.

string GetSenderEmail(Outlook.MailItem item)
    {
        string emailAddress = "";
        if (item.SenderEmailType == "EX")
        {
            Outlook.MailItem tempItem = (Outlook.MailItem)Globals.ThisAddIn.Application.CreateItem(Outlook.OlItemType.olMailItem);
            tempItem.To = item.SenderEmailAddress;
            emailAddress = tempItem.Recipients[1].AddressEntry.GetExchangeUser().PrimarySmtpAddress.Trim();

        }
        else
        {
            emailAddress = item.SenderEmailAddress.Trim();

        }

        return emailAddress;
    }
