i am trying to setup RPC over HTTP on a outlook 2007 environment.
i have installed the certificate under trusted certificate authority and under local computer specifically, and the import was successfull. the OS i have is windows vista business. i have configured outlook the same way i did it on a windows xp OS SP2 where it worked fine.
Whenever i open outlook, it prompts me for the my username and password, after that i get the message:
"There is a problem with the proxy server's security certificate.
The Security certificate is not from a trusted certifying authority.
Outlook is unable to connect to the proxy server www.*******.co.uk.
(Error Code 18).
