Recently, I've noticed that some recent emails that I've sent from my phone have appeared fine in my sent folder on my phone email account however when I access it on my computer, the sent folder has multiple copies of the same emails (i.e. the ones sent from my phone) that are being sent every few minutes from the looks of it. I've asked one person who I've sent a recent email to from my phone and they've said they haven't received multiple emails from me, however I don't know about the others. Has anyone else had this problem? This is HOTMAIL, not Outlook, I couldn't find the Hotmail topic in the dropdown menu,

Thanks for any help
