How many SSL certificates do I need for Exchange 2010?

You can have just one, you just need to plan the deployment right. You need to consider if you will have a TMG server, if you are using a CAS array and so on. If you provide a little more information we might be able to give a more exact answer. /MartinExchange is a passion not just a collaboration software.

Single CAS server, no TMG or ISA just the firewall. I've heard (read) you need multiple certs for the different services (Autodiscovery, OWA, ActiveSync, etc). What other info do you need? Thank you

Normally I use one certificate for these deployments, but you need a SAN certificate. More about them for MS here: http://technet.microsoft.com/en-us/library/dd351044.aspx Also a bit information from digicert here: http://www.digicert.com/ssl-support/exchange-2010-san-names.htm And of course a bit of easy information is just using the certificate guide that is built into Exchange 2010. If you mark "Server configuration" in the management console you will have a "New Exchange Certificate" option in the Actions pane. If you follow that it will generate the request with the names that you need. These are the names i normally use: autodiscover.domain.com webmail.domain.com FQDN on server NETBIOS on server /Martin Exchange is a passion not just a collaboration software.
