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.

You should create a new certificate as the error says to do. or use a 3rd party/Internal trusted PKI cert if required.  ( You have some time 2018 hours)

Hello Andy,

Thank you very much.

Yes I check my certificate in my Exchange server and I found my GoDaddy certificate is going to expire in the next 2018 hours.

again Thank you very much for your time.
