Hi,

you must disable FBA on the Exchange Server if you want to use the default OWA VDir on the CAS Server, else you must create a additional vDir on the CAS Server where FBA is disabled and redirect the TMG publishing to the new vDir.

Hi Quan Gu,

I have changed from Forms based to basic authentication. It still having TMG logon page instead of OWA logon page.  Double checked the publish OWA, it seems configured correctly.

Before the changed the Forms based, it has double logon pages. eg. TMG logon page -> OWA logon page -> email.

After the changed, it become TMG logon page -> email.

Regards,

I have resolved it after enabled Use customized HTML forms instead of the default under Application Settings tab.
