Problem accessing OWA online and setting up Outlook in Mac

Hi,

I am having a couple of problems with Outlook in my Office 365 Education account: 

1) I can't sign in to outlook online at https://outlook.office365.com/, I get the following error message: 

X-ClientId: 0DMB - IKEQ - NKCK - NVOG
X-OWA-Error: Microsoft.Exchange.Data.Storage.UserHasNoMailboxException
X-OWA-Version: 15.1.16.15
X-FEServer: SINPR06CA004
X-BEServer: BN1PR07MB309
Date: 11/10/2014 6:23:29 AM

2) I can't setup up Outlook on my Mac. I'm following these instructions : "Set up Outlook for Mac 2011 to work with Office 365" from this website:

support.office.com/.../Use-my-current-Office-for-Mac-apps-with-Office-365-c113166e-9491-46ef-aadb-9ca75112baff

I get an error at step 10 because Outlook is unable to find the exchange server. Then I get a text field in which I need to enter the server's address. I see the following message under this text field:

"Account cannot be added. Note that Outlook 2011 requires Exchange Server 2007 SP1 Update Rollup 4 or later."

Would appreciate help with this. 

Thanks,

Rohit
