send and receive emails multiple copies

I have an issue whereby when sending emails, I have windows 7 premium I installed and created hotmail  with live essentials I think.

I have looked at account settings instead of seeing incoming and going ports with port numbers, instead all there is an url address which doesn't allow to manually input port settings. This has be going on for awhile 18 months or so, recipient are getting annoyed with me and blocking email address. I don't know whether I was downloading something or creating something,  I have checked settings as mentioned while in live essentials for answers ref settings. Also when I have gone in direct via hotmail it still doesn't show ports and No just url. I created documents transferred all e-mails  from live account and talktalk also gmail. Uninstalling live essentials and then reinstalling essentials send and receive emails still receive duplications still there, talktalk account is a pop account settings there gmail account is an imap settings. With having smart phone sending e-mails via live account still have duplicatings. But noticed live hotmail acoount setting s showed settings through imap incoming and outgoing ports with numbers. I assume that with live account on phone showing settings imap that possible that settings on pc might also be imap. Can someone suggest what to do to fix issue,  could it be if I had incoming and outgoing setting ls for hotmail account might fix problem.  Would appreciate any help regards brionypups
