    Look here and here for guidance.

    That will help you with how to modify the forms. Reading the first link (unsupported scenarios) this may be close to unsupported but as long as you do not add functionality...

    EDIT: your form is presented by the TMG Server publishing Exchange and any changes needs to be done there. The other option would be to skip pre-auth on TMG and let the published server do the authentication (nothing I recommend, but can be done).

    Just a bit more info my Exchange TMG setup is as follows:

    Exchange Client Access ------ TMG1 Server with OWA Publishing rule--------------------------TMG2 serving client requests
    OWA uses                              Listener uses HTML Forms Authentication                               Website publishing rule for TMG1
    Integrated Windows Auth        Authentication Validation Method - Windows                           Listener has no authentication method set (all HTTP requests are 
    With Basic Authentication                                                                                                     redirected to HTTPS)

    Anders,

     I couldn't find anything that specifically addresses the public\private question. You could be right about the unsupported scenarios, but that article is dated 2009 - I think some of those scenarios have changed (i.e. Edge Transport with TMG is supported).

    I'd be surprised if proxying an SSL OWA connection isn't supported - it seems like a straightforward and reasonable thing to do.

    That is absolutely true, but I did say guidance. :)

    You'll have to dig into the code and test, the second link provided tells you how to create a custom forms set, the one you want to copy is the \%Forefront TMG Installation Directory%\Templates\CookieAuthTemplates\Exchange directory.

    Start by looking at the usr_pwd.htm file and search for the string L_ShowPublicUI_Text and L_ShowTrustedUI_Text (these constants are replaced with text from strings.txt) and work yourself from there. That will start you in the right place.

    You will not find a complete guide for this, I haven't tried this particular configuration for myself but you are dealing with regular htm pages so it isn't that difficult.

    For anyone else who wants to do this:

    There are 4 html files in the TMG installation folder under Templates\CookieAuthTemplates\Exchange\HTML:

    usr_pwd.htm, usr_pwd_pcode.htm, pwd_pcode.htm & pwd_pcode_nxt.htm. 

    Edit these files by finding "rdoPrvt" element and set the input type to hidden.

    Then open up the appropriate strings.txt in the nls folder for your language.  Comment out\alter as needed the following:

    L_ShowTrustedUI_Text - This is a private computer
    L_ShowDetail_Text - (show explanation)
    L_ShowTrustTitle - displays security

    If someone figures out how to remove the brackets in "Security (show explanation)" that would be helpful - couldn't find it in the HTML or strings.txt.
