If you want to change the FQDN of the send connector, then after that, you have to issue a new certificate to the new FQDN. Please try to &nbsp; ensure that FQDN of your send/receive connector is also listed as a subject name or subject alternative name on your certificate, and after that you need to enable the certificate for SMTP service.<br />

I have recently set up a single server in our lab to look at the possabilities of using exchange 2010. <br />
<br />
Is there a way to change the FQDN in the helo message. &nbsp;When I telnet the current FQDN is servername.testdomain.loca<wbr />l. This was easy to do in exchange 2003.<br />
<br />
TIA<br />

In addition to well-known products like SQL Server, Exchange, Internet Information Services (IIS), Microsoft Dynamics, Forefront, Lync and Sharepoint, they include applications like Skype, BizTalk, Hyper-V, Groove and Commerce Server. Server applications are managed with the Microsoft System Center.
