TMG - Exchange 2007 OWA Form

Hi guys,

We have a TMG for use with 1 customer.
The customer has Exchange 2007 and TMG 2010.

The default TMG Exchange publishing is showing up as Exchange 2010 Outlook Web App main login page.

When user types: https://webmail.domain.com/ it works fine. (Exchange 2007 form)

When the user types: https://webmail.domain.com/owa it shows (Exchange 2010 form).



When connecting from the outside, Exchange is published through TMG and the forms used are set to default of 'Exchange' in the Web Listener.


To handle HTTP requests, theres a rule to redirect to https://webmail.domain.com/owa


However, when typing that address into the browser manually https://webmail.domain.com/owa it shows up as Exchange 2010 form.

What I need to do, is keep it consistent across the board and have it all showing as Exchange 2007 if possible.

Do I need to edit the templates for this in TMG 2010?
Would taking a copy of the ISA 2006 Exchange directory (which is an Exchange 2007 form):

C:\Program Files\Microsoft ISA Server\CookieAuthTemplates\

and put them on the TMG under:

C:\Program Files\Microsoft Forefront Threat Management Gateway\Templates\CookieAuthTemplates\
under a directory called "Exchange2007"

Then adjust the Web Listening to default the forms to 'Exchange 2007'?

Will that work?
