First I thought it was a mobile synchronize problem but after log in on a desktop then the message appear
"that probably someone else is using the account."
I've read that, See http://t.co/H4CWkhIsUX Sunday the 18th after this message, what probably was the basis for the problem. 

Then tried to restore/ recover the account and filled in the recovery forms several times this past week but after the first received a notification that MS is investigating was with no result... Searched contact by Twitter and they pointed me to this site... 

I did put this question under http://answers.microsoft.com/en-us/windowslive/forum/liveid-wlsecurity/unable-to-access-account/b2f67520-54cc-4180-b1cb-f5b004836cf4 but after half a week a confirmation from Twitter MS Support that it probably is in a wrong forum??
I put it under Security and Permissions but now I choose than Profile and account details.

This morning the 27th, so 10 days later, I received a message that after this several times trying to recover it wasn't possible to gain
a recovery access and I have to make an new account....???

This is an advise which i.m.o. is not the solution. We can do better than that... 

I suggested also already that MS should call me to indentify me as the real owner but this wasn't possible with this "free" account type.

So hereby again an urgent request for help to let me use and recover my MS mail account again after more than 12 years using it.

Thank you !!
