Sorry, we don't find any difference between your code and our code in default event handler. We use following method:
Code: Select all
protected void SendEMail(string subject, string body, string filePath)
{
try
{
MAPI.SendEMail(subject, body, filePath);
}
catch (Exception e)
{
StiLogService.Write(this.GetType(), "Send E-mail");
StiLogService.Write(this.GetType(), e);
if (!StiReport.HideMessages)MessageBox.Show(e.Message);
}
}
I have only one recommendation, try to use our code directly. You can find full version of MAPI class above:
