I just installed an addtional Exchange server in my Exchange Org. The Org started out as 2003 but I have added a 2007 server that has the CAS, HUB and Mailbox roles running on a 2008 server. All is working except OWA externally. while I know i have not install the web cert on this box as of yet, i would think that OWA should still work. From an external client I goto the web address of the OWA server, i get the cert warning, i click continue and then get the following message:
The URL you requested has been blocked. URL = invalid.
I know the my firewall is configured corectly as I am getting email on port 25, i can RDP in on port 3389 and i get the cert warning page, all of which are on the same box. I have made sure that the interal and external address is the correct within Exchange Management console for Server config and client access.
any help would be greatly apprecaited.
