HELP! I cant receive emails in my hotmail/outlook.com account

Yesterday morning I was able to receive messages(junk and inbox) and starting last night I have not been able to receive ANY.  I have tried sending a test email from the account to myself, from my husbands hotmail account, our mac mail account and nothing has worked.  I can still send emails out.  I have not made any changes to the account or our computer.  I have also tried from 4 different devices.  My husbands hotmail/outlook account is working just fine.
