If this host does not host any other virtual hosts, then: no, you don't
need all the names.

But beware: Outlook insists on using only HTTPs, so you need a valid
certificate with the correct name for _every_ hostname.

Better use of a SRV record in the DNS to redirect all Outlook requests
to only one hostname.
