Tom,

Thanks... I had just reviewed those. *8^)

The / to /exchange\ worked but didn't.  I get a user challenge (probably
configuration on the OWA server itself).

I got the protocol redirect taken care of.  Now it's just the path.  I
lost where Jim was going with his last response.

I have to base the redirection on a different ISA error.  Mine is 12202,
not 12217.

If the error is 12202, doesn't that mean I create a file in the
ErrorHtmls directory named 12202.htm and populate that file with the
redirect?  I'm not sure where the 12217 number came from. *8^(  My
apologies for my denseness here. *8^(

Cordially yours,
