Hi,

We cannot access OWA from outside due to an incorrect certificate that is assigned to the url. OWA works fine from internally and the correct SSL certificate is assigned to the url. We have a freebsd server on our network that routes and receives mail from externally and routes it to our mail marshall server. I think that the incorrect certificate is so how configured on the freebsd but i do not have good linux skills to check and confirm my suspicion.

Regards
Tinus

Check the connectivity using below link.

Check DNS record for owa.domain.com point to the correct ip.
And verify in the firewall that the port for HTTPS (443) is opened .

the certificate URL and the URL created at ISP should match and pointed to the external IP address which should be natted to the internal exchange ip.

443 and 80 should be open on the firewall.

Incorrect certificate binding will not block owa.. It will give you a warning message.

Check port 443 from external and make sure that it's configured to be forwarded to the correct  ip.
