I have tried the above Enable-ExchangeCertificate<wbr /> but get the below error <br />
<br />
<br />
Warning: This certificate will not be used for external TLS connections with an FQDN of mydomain.com because the CA-signed certificate with thumprint 'C80BB0395FFE4D4258F6895B7<wbr />41C838BFAC<wbr />B' takes precedence. The following connectors match that FQDN: Default MYSERVER, Client MYSERVER<br />
<br />
<br />
The certificate which has expired was valid for SMTP services. The certificate the above Thumbprint is referring to is valid for IMAP, POP and IIS so I can't see why it takes precendence<br />
<br />
I am still getting Errors 12014, 12015 and 12016<br />
<br />

Hi Experts<br />
<br />
I keep getting Event ID 12016.<br />
<br />
The existing certificate for that FQDN has expired.<br />
<br />
I have tried created a new using New-ExchangeCertificate task but may not be using that correctly since error keep showing in Event log. Any ideas?<br />
<br />
Thanks
