[horde] horde activesync with outlook

[murali at itechservices.in]

Hi
   With the help of this link 
http://wiki.horde.org/DebJessieHorde5?referrer=HowTo i have installed 
horde 5.2. I am able to sync all including mails with mobile devices and 
trying to configure outlook2013 to sync calender and contacts via EAS, 
but it gives error 'logon to exchange activesync mailserver(EAS) the 
server can not be found'.Does outlook allow to configure EAS account for 
horde? or do i miss something  if yes can anyone help me with the 
details.

Thanks in advance
