| Description | RPC to server (MAILSERVER) failed with error code (6d9). |
| Event Information | Cause: It turns out the certificates common name was just the host name (e2k3srv1), not the FQDN, while your Outlook profile was configured to use the FQDN (e2k3srv1.e2k3test.msft). Resolution: It appears Outlook didnt like the fact that the certificate didnt match the name you gave it; when you changed the Outlook profile to use the host name, it will start working |
