Hi All

I am having this error when accessing the OWA Website:
The security certificate presented by this website was issued for a different website's address.

What should the certificate name be to avoid this error?

the certificate should have the same commun name as the URL you use to access OWA

I recommend a SAN or UC certificate.


One of the most important aspects of a successful Exchange messaging deployment is how you configure your SSL certificates for securing client communication to your Exchange infrastructure. This is because all communication between Outlook clients and the Autodiscover service  endpoint, in addition to communication between the Outlook client and Exchange services, occurs over an SSL channel. For this communication to occur without failing, you must have a valid SSL certificate installed. For  a certificate to be considered valid, it must meet the following criteria:

- The client can follow the certificate chain up to the trusted root.
- The name matches the URL that the client is trying to communicate with.
- The certificate is current and has not expired.

Remember,  the cert request needs to be generated by Exchange using PowerShell.

When you get the response back from the CA, use the import-certificate command to process  and enable it for SMTP, IIS, etc.

If you use public certificate please provide error message when you brows OWA.
If you do not want to use certificate just go Inetmgr and select OWA directory and remove SSL option.

to generate a certificate and you get no warning when used it, it must acheive 3 conditions

1. the certificate is issued by a trusted certificate authority, by other words, the client who the request the page must trust the issueing certificate authority
2. the certificate validity times, valid from and valid to dates
3. the certificate CN name must match the requested URL
to do so, go to https://www.digicert.com/easy-csr/exchange2007.htm
and put your URL for example, mail.domain.com in CN name and alternative names
