Jose Osorio R. said:when Im accessing to OWA or Outlook Anywhere there is a problem with certificate.What is the "problem"? What is the exact wording of the error message displayed on your browser?Also who is the CA? is this a AD CA or a publicly trusted one?Mike Crowley: MCT, MCSE, MCTS, MCITP: Enterprise Administrator / Messaging Administrator

Hi Mike,With the New SAN Certificate on Exchange Server 2007 I'm having the following issues:First:WhenI access to OWA the Browser show me this "There is a problem with the security certificate for this website". I didn't have that problem with the Old Cetificate.Second:I can use Outlook Anywhere, but when I start Outlook Anywhere it show a warning windows "is a problem with the security certificate for this website"The CA is in DC?When I checked SAN Cerificate in Properties Tab / Detail Tabs /theSubject Alternative Name field is with warningsymbol.But as I said when i put the Old certificate on Exchange Server, Everything is OK.Thanks.

Hi, When you receive message indicated "There is a problem with the security certificate for this website", you should get more information indicate: 1. Whether the security certificate is from a trusted certifying authority. 2. Whether the security certificate has expired 3. Whether the name of the security certificate matches the site you attempting to access If certificate is not trusted, has been expired or its name dos not matches the site you attempt to access, you will receive the error. Therefore, would you please help me gather more information regarding the error? You can capture a screenshot to me (v-mishen@microsoft.com) when the error is encountered in OWA and Outlook Anywhere.
