today I saw that the exchange certificate I imported for OWA has the following status:
The Certificate Status could not be determined because the revocation check failed
The certificate is from ou own CA which is located on our local network and it is for POP and IIS. When I created the certificate everything worked fine and the status was OK.
Now that the status is as described also everything seems to be working fine. The OWA-Website can be accessed using https without certificate-warnings.
So now I found some articles about wrong WinHTTP-Proxy-Setting.
OK, we have a proxy-server but it is not configured for the exchange server. The WInHTTP settings on exchange show "direct connection".
We made changes to our network infrastructure some weeks ago (supertnet, new DHCP-ranges, moved CA to anather server).
Could those changes be responsible for this issue?
Of course I can set the WinHTTP-Proxy settings to our proxy server but I don`t understand why I should do this. And our proxy requieres authentication...
Has anybody a hint what I could do?
Thanks a lot.
