Hi, as you can see on your posted images the certificate is issued to '*.wadns.net'. When outlook connects to your server is uses the 'autodiscover''  feature to collect information about your server. The autodiscover URL is set to 'autodiscover.smms.ac.za'. This name is not on the certificate (*.wadns.net) and therefore you get an error that the certificate is found but the name is not correct.
If this is an UCC certificate then you should be able to add alternative names to the certificate. Add 'autodiscover.smms.ac.za' to your certificate, install this new certificate and the error will go away.
Otherwise here are other options for your situation (scenario 4):

Did you understand what I posted? This is a name-on-the-certificate-problem where the name on the certificate doesn't match the domainname that it is installed on. The proof is in the screenshots.

Please let me know if the problem still exists. You have multiple options to fix this problem, depending on the server(s) configuration. You need to make sure the correct name exists on the certificate (you can have a certificate with multiple names) or redirect the autodiscover in dns to the correct server so outlook can see it needs to validate another name. Both options can fix the problem. I would go with the first option and purchase a multi-domainname-certificate (called UCC) because that is the most accepted solution for devices like phones, handhelds, etc
