OWA and OMA does not work externally because certificate won't install on ISA server
Posted on 2009-04-16
I had an old certificate setup for use with my OWA/OMA and RPC over SSL. Because of certain circumstances, I was not able to renew it when it expired and I had to purchase a new one from the same seller, revoke the old, and install the new. When I install the new certificate it allows access to OWA and RPC over SSL when connected to the network ONLY. I have an ISA firewall in place and I deleted the old certificate, but I cannot get the new one to use email authentication as one of its purposes so I cannot connect to OWA or OMA or RPC over SSL externally, it is grabbing the old cert and stating that the cert is expired.
