Hi, What is the event ID that you are getting & also post the full error if possible.Ripu Daman Mina | MCSE 2003 & MCSA Messaging

You can set the FQDN to match the certificate subject name with : http://technet.microsoft.com/en-us/library/bb125140.aspx Don’t modify the FQDN value on the default Receive connector Default <Server Name> that's automatically created on Hub Transport servers. If you have multiple Hub Transport servers in your Exchange organization and you change the FQDN value on the Default <Server Name> Receive connector, internal mail flow between Hub Transport servers fails.
