reset my account

Hello

Weeks ago, I decided to change to gmail because I thought that Outlook.com had become very slow to use.  I created an account and transferred my emails across using online guidance.  I setup a forwarding to gmail within my Outlook.com

I then realized I would have to change my email address on many different sources and actually this would not be worth it, so I transferred my mails back to outlook.com and put a forwarding address in gmail

I now have a VERY confusing outlook.com account which is making me regret ever doing this

- My emails are in a POP folder instead of my inbox

- New emails are going to my inbox AND the POP folder

- I now get multiple copies of new emails

I have tried to correct this but have failed to to do and I do not understand lots of the settings anyway.  If I cannot correct this, then I want to know how I can reset my account and start again with an empty mailbox (I have no contacts or other information I want to save)

Regards
