ECP login deny - redirects to OWA


  • my scenario is following :

    exchange server 2010 (CAS and Mailbox roles)

    Install a new Exchange Server 2013 one mailbox role and one server for CAS role.

    now login problem at new server first it redirests me to old admin console .. i solve this issue by adding 

    ?exchclientver=15. in url .. but still its redirects me to owa and sometimes says username password error .

  • Hi,
    While your mailbox is stored in EX10 you need to use  the URL */ecp?ExchClientVer=15 and later when its moved to EX13 and you want to access /ecp in EX10 the url to use is /ecp?ExchClientVer=14

    If you have problems with this...Use an account with proper permissions that doesn't have a mailbox.
