CRM 4.0 outlook client always redirecting to http instead of https

Hi,

We have configured outlook client for CRM 4.0 using https URL but when we use CRM outlook client it is redirecting to http automatically (all the records URL opening with http). We have created SSL certificate to access CRM through https without IFD. Is there any specific reason that it is taking http always. Also when we access https through web browser it is working properly.
