I've just installed Outlook 2013 and have all the clients connecting to it, however, whenever a client connects via outlook they are prompted with an invalid SSL message for
myserver.mydomain.local. I have a wildcard certificate setup and assigned in IIS for
*.example.com so I understand why the message appears but I am not exactly sure what to do about it and where to start looking without poking random things.
From the research I've done, I can see that this can be caused by the autodiscover service so I have changed the domain DNS records to not use an A record but instead use an SRV record inline with this Microsoft article. Should this be sorting the issue and I am just being impatient with propagation or am I barking up the wrong tree?

Edit Interestingly running
get-ClientAccessServer | ft identity,AutodiscoverServiceInternalUri shows my internal FQDN and not my external one which I assume is the issue. I am going to try changing this now.
