i cannot access hotmail and receive the upating inbox message for over 24hrs despite nearly 3 hrs on tech support i cannot resolve this issue for email access

I cannot access Hotmail inbox after purchasing a Microsoft tablet and linking it to my existing Hotmail account. I get the updating inbox message for over 24hrs and tech support have not been able to help after several hours of exchange. I can access the account and change settings etc but not the inbox- any advice?
