Office 365 with Outlook 2011

I am having problems setting up an Office 365 Exchange account on Outlook 2011 for Mac.

I type my email address and password and it sucsessfully gets the right server by using autodiscover.

I have also tried entering the servername manually be after getting them from OWA.

I have no problems connecting my account to iOS devices or Outlook 2010 for pc, so i assume there is noting wrong with my account or dns.

I get the same error on both my Macbook Air and iMac. It sucessfully authorizes the username and password, but it does not start syncing the folders.

I have also compared the settings Outlook gets from autodisover with an other account on another domain and it is the same.

Does anyone have any suggstions?

Thanks in advance!
