Deleted emails keep coming back, iPhone 5

Question

On my iPhone 5 I have deleted 4 emails from my inbox but every time I refresh the page the emails return.
When I close the email app after deleting them the red icon shows 4 new emails.
I can’t get them to actually delete. What is causing this and how do I get rid of them completely?

Answer

I had this too. What I did was just kept trying over a couple of days and eventually it didn’t come back.
I deleted my Hotmail account off my phone and went onto Hotmail on the computer and checked the emails where actually deleted.
I think it came from when there was no internet connection on my phone and I deleted the emails then and somehow it must have corrupted the information so it kept coming back.
