Hello,
We installed Exchange Hybrid Server 2010 to be used for O365 migration. Also, got the new cert from Godaddy for the Hybrid and ADFS. cert name is hybrid.domain.com. The cert is new and wasn't re-keyed or reused.....

All of the sudden, all the users getting an error in Outlook referring to the cert we just installed on the Hybrid Server - hybrid.domain.com

Since we didn't reuse their existing cert and the users NOT suppose to be using the Hybrid Server for anything...Why are we getting the cert error?? Their existing servers are Exchange 2007 servers and Hybrid Server 2010 was just installed. Nothing suppose to be going through it. The cert is new and was installed on the Hybrid server only.

THank you very much

Did you install the intemediate certificate?
When they get the error it should say what is happening - probably the name on the certificate doesn't match something in Exchange.

Go through Exchange and ensure that all of the host names match your SSL certificate host name: http://semb.ee/hostnames
