"Page Cannot Be displayed" at OWA Logon

Im not sure if there is an issue with the certificate or what, but when accessing OWA externally i get as far as clicking continue when you recieve the message about the certificate not being trusted. Once i click continue i recieve page cannot be displayed.

Internally OWA works flawlessly, just out of network it doesn't. If anyone can help me i would appreciate it. Also i've checked if port 443 for SSL is open and pointing to the Exchange server. In this case it is.

I am assuming you have a public ip associated with the owa address for you organization?

Can you enter the ip address to your owa in a browser and let me know the results

Also check your dns server logs for any issues regarding IIS on your exchange server, and check your exchange servers' event viewer as well

i forgot to note via MS best practices i installed this on a member server to avoid any issues. I ran into trouble installed Exchange 2007 via unattended mode but couldnt bc it couldnt find the AD. Resolved that issue by recreating the Zone. Once i got that going everything else fell into place and it installed cleanly. As far as i can see DNS is throwing out any red flags nor is the event viewer on the exchange server giving any warnings.

I did a nslookup and ran into the defualt server uknown, but just resolved that as well by doing ipconfig /registerdns. Thought it would fix the external OWA issue but still no luck.

internally it does via https://local-ip/owa you get the not trusted certificate but once you click continue you can login to the owa perfectly fine. Externaly via https://wanaddress/owa  once you click continue for the untrusted certificate you get the page cannot be displayed message.

Hi,

Have you applied any exchange updates recently?

Also does your exchange is updated with the latest service pack? If not, then update it.

Hope this helps,
Shree

Make sure that your have ports 80 & 443 open on your internet router and redirected to the server if you are doing NAT.

Ill try doing the update today shreedhar, uescomp as for the NAT, ports 443 and 80 are forwarded to the exchange server already. They are in fact open, i used 2 port checkers and they show as opened.

Ok, got it to work. Looks like 443 was conflicting with another service on the sonicwall. Changed the port in IIS to **** and OWA works. Can someone help me out with the Outlook Anywhere portion?

Shreedhar EtteCommented:
Hi,

The OWA has to work on the default port of 443. Request you to change the Sonic Wall to some other port.

I would request you to post another question for the Outlook Anywhere.

Hope this helps,
Shree

Yeah i changed the port back to 443 last night and removed the https managment from one of the ports on the sonicwall that was causing the conflict. OWA now works on port 443
