iCloud and me.com issue 'over quota'

Hi there,
Does anyone have a clue how to stop the following problem? I do not wish to use this me.com address and all my emails to this account are being affected. I have been in to see the Genius Bar and unfortunately this problem is still occurring.

I am also unable to work out how to access this me.com account in order to get rid of it so I would appreciate some ideas if you have them.

Help?

Thanks so much. I will have to make another appointment to see a genius but I thought perhaps someone might already know how to answer this.

iCloud and me.com issue 'over quota'

Hi Bear,

Yes, it's my account. When the iCloud thing came about I thought I'd give it a try and I didn't realise until just a couple of weeks ago that whenever I send an email from my iPhone, it sends from either @me.com or @icloud.com and I don't get any other options. So it's been sending from here for a while I suppose.
Any idea how I can gain access to the @me.com account? I can't even remember how I ended up with it in the first place

Thanks!

Miriam
