I need to add an Exchange 2013 server as a Hybrid in an existing environment with existing 2007 Servers. Are there any gotchas that need to be avoided? Currently they don't have an autodiscover record I know when 2013 will be installed Outlook might not connect correctly for hosts as it will give them cert errors. We are planning on getting a new UC-SAN cert for Exchange 2013 server but it might take some time to apply it. How do we deal with cert error till then?
Also do we need to replace existing cert on 2007 Server with new cert as old cert does not have autodiscover record in it
