ISA 2006 Publishing SSL Sites

[ICTNUT]

I am trying to get my OWA SSL'd but I am running into problems.

 

Acroding to various sites I need to import the SSL cert from my exchange server into ISA 2006, which I have done, but when I try to create a Published site using the OWA publishing wizard ISA tells me the cert is invalid and Ican find no reason why.

 

Has anyone successfully published OWA SSL via ISA 2006 or run into the same problem.??
