My exchange 2010 certificate is expiring today, and since the previous (self-signed) certificates were a complete mess, i decided to buy a new ssl certificate from an official source.
Since there are a few domains on that exchange server, i went for the comodo ucc san ssl certificate which covers 4 domains.
My questions are as follow:
1) Can i delete all existing certificates on the server, and install the new official one? How is it done, keeping in mind the server has domain1.com (mail.domain1.com ), domain2.com (mail.domain2.com), and myserver.mydomain.local for the local machine.
2) Do the clients currently connected to that server need to do anything to update the certificate?
