There is a registry setting that needs to be done on the OWA server. I
found this fact the other day and finally resolved my OWA issue. There
is a KB article that talks about the reg key update. It is the scenario
where you have an SSL off-loading device.

http://support.microsoft.com/default.aspx?scid=kb;en-us;327800

The scenario: OWA receives the request and doesn't realize that it's an
HTTPS request, so replies with the various component URLs as HTTP://
instead.

No, this is not an endurance test....(not for you guys anyway!)

Someone had suggested that ISA needed to be the gateway in order to
proxy the connections - I've since proved this to be incorrect by
testing it in straight http which works.

I've also found in the log at connection:
protocol: https action: failed connection dest: ISA source: client HTTP
status: authentication required.... log record type: web proxy the weird
thing is the URL is: http:// etc.. NOT https.
then a connection:
protocol: HTTPS initiated connection etc.. from the 'firewall' log
record type

Appears it may be a problem with the certificate but it's not showing
itself very easily..
