The solution is editing the web.config file and change the requireSSL=”true” to “false” , see the steps below :

Find the Outlook Web App Web.config file on the Client Access server. The default location is Program FilesMicrosoftExchange ServerClientAccessOwa.
Make a backup copy of the file (Important!)
Open the original file using Notepad.
Find httpCookies httpOnlyCookies=”false” requireSSL=”true” domain=”” and change the requireSSL flag to false.
Save and close the file.
For the new settings to take effect, open a Command Prompt window, and then type iisreset to restart IIS.
