whether the symptom occurs on an Internal Outlook client or an external Outlook client. If it occurs on an External Outlook client, I think we are using Outlook Anywhere and we have to add the “mail.abc-company.com” to the domain names in the certificate. If the error occurs on Internal Outlook, we can workaround this issue by turning off “Outlook Anywhere” by: 1. On a problematic Client, open Outlook. 2. Click Tools >> Account settings. 3. Double click the profile name and click More Settings. 4. On the Connection tab, uncheck on “Connect to Microsoft Exchange using HTTP”. 5. Save the changes and restart the Outlook to check this issue.

Creating your account only takes a few minutes. Join Now Good morning all, I was just notified by a user this morning (my boss) that she is unable to connect to Outlook on our Terminal Server. She is the only user with this issue. She is using Outlook 2010 and uses this Terminal Server very frequently. The error reads: There is a problem with the proxy servers's security certificate. The name on the security certificate is invalid or does not match the name of the target site [server.domain.com]. Outlook is unable to connect to the proxy server. (Error Code 0). We don't use a proxy server, nor is there any certificate that I'm aware of. Exchange isn't my strong point, so I was hoping you guys could help point me in the right direction!
