Hi There,
I have upgraded my Exchange server from 2007 to 2013 in Jul 2014.
in my 2007 structure I used to have an Edge Transport and two Hub servers.
but in 2013 I got rid of all of them and have only one server.
Now I am getting Errors below:
Event ID 12017
An internal transport certificate will expire soon. Thumbprint:D23A8F92E7F?????699964B098C318EA57E0A824, hours remaining: 2018
Event ID 12018
The STARTTLS certificate will expire soon: subject: email.mydomain.com, thumbprint: D23A8F92E7F?????699964B098C318EA57E0A824, hours remaining: 2018. Run the New-ExchangeCertificate cmdlet to create a new certificate.
Shall I do anything? or I receive the message because I ran my exchange server 2007 next to my 2013 for a few months.
