Question : OWA 2010 published through TMG 2010

Hi All,
I have published our OWA 2010 portal externally through TMG 2010 and it works fine.
I had previously customised the logon page on the CAS servers and this works ok and shows the company logon, but the external page published through TMG  has the default logos and I cannot find where to change them?

Is the OWA page also stored on the TMG gateway server, or should it be presenting the internal OWA page with the custom logo?

Thanks,
Mark
