Hi! One more case of "Error: Either Exchange server requires secure connection or account is disabled" here. 1. Exchange 2007 in used 2. Allow non-provisioned is enabled 3. I have installed our (self signed) root certificate that is used to sign the cert on owa server. It is visible in cert store in the settings section with server, wlan and email enabled. 4. Changing language does not help. Still the error comes every time I try to enable MfE. Why does not it work? Any ideas? When will this be fixed?
