I have got few certificates .
1. "Microsoft Exchange Server Auth certificate" ,
3.Exchange Delegation Federation.
certificates which are going to expire soon on CAS SERVER 1,CAS SERVER 2,MAILBOX SERVER 1 & MAILBOX SERVER 2 of my exchange server 2013 Enterprise in DAG .Each certificates on all of my 5 servers have same Thumbprint,same Serial numbers & same public key size .
So what i did was i went to exchange ecp Servers>Certificates and selected "Microsoft Exchange Server Auth certificate" of mailbox server 1 and clicked "renew" button from right side pane after few second a new certificate with the name "Microsoft exchange server Auth Certificate" was created with 5 years extended validity . My question is should i do the same process on all of my other servers (Mailbox server 2 ,cas server 1,cas server 2) or should i export the certificate from mailbox server 2 and import it to all of other exchange servers .
Please enlighten me which procedure i need to follow and will the same be applicable for other 2 certificates as well (that is certificate with the names "Microsoft Exchange" &
"Exchange Delegation Federation".)
Please find attached screenshot for your reference.
