Here are the default permissions for the Exchange virtual directories:

I found that the print in the screenshots was not clear - maybe it's me or my browser.
What names do you have on the certificate?
exchange.abc.local
Is that it?
Is this a self-signed certificate? Or did you get it from Digicert, VeriSign, GoDaddy or some other 3rd party authority?
Regardless, the URLs for the virtual directories, OWA in particular, have to match what is on the cert.
So OWA might be:
https://mail.exchange.abc.local/owa
Other possibility:
https://webmail.exchange.abc.local/owa
Since exchange.abc.local is what you have on the cert, the URL has to configured as shown above. You can use "mail", "webmail" or whatever just before (once again, as shown above) but you have to make sure that is what the users enter
when they attempt to access email.
