Unable to send mail in the send folder when using e-mail account from browser but can view when using Windows Live Mail.

Original title:  windows 10 live mail

I  sent the email with attachements from  windows 10 live mail. I can see the email in the sent folder in windows 10 live mail but when i opened it from internet explorer i am not able to see the email in sent folder. Which one i need to follow and to be sure that the email is sent? Or is my email still not sent? Any ideas or walkthroughs are highly welcomed.
