Remove The Basic Or ‘Light’ Option Checkbox From The Microsoft Exchange Server 2010 Outlook Web App FBA Logon Page

This article describes how to remove the ‘Use Outlook Web Access Light’ option on the Exchange 2010 OWA Forms-Based Authentication logon page. As usual, there’s no built-in way to do this, but it’s possible with a fairly simple modification to the FBA page source.

First, look for the OWA 2010 FBA logon.aspx file in the C:\Program Files\Microsoft\Exchange Server\v14\ClientAccess\Owa\auth folder. Make a copy of it (important if something goes wrong), and then open it in Notepad. Press F3 to search for text, type chkBsc, then Enter. You should see a few lines that begin like this:

<tr>
  <td><input id="chkBsc" type="checkbox" onclick="clkBsc();" disabled...
  <td nowrap><label for="chkBsc"><%=LocalizedStrings.GetHtmlEncoded(Strings.IDs...
</tr>

What you have found is the code that produces the checkbox and the text beside it.

If you delete these lines, the checkbox will not appear; but the safest way to remove it (in case you want to undo this in the future) is to place HTML comment tags (<!– and –>) around the <tr> and </tr> tags . After doing that, the section of code should look like this:

<--<tr>
  <td><input id="chkBsc" type="checkbox" onclick="clkBsc();" disabled...
  <td nowrap><label for="chkBsc"><%=LocalizedStrings.GetHtmlEncoded(Strings.IDs...
</tr>-->

You should find that the ‘Light’ checkbox no longer appears.

As with most of these type of modifications, you will need to check that they still function after each product update. Sometimes your modified file will be replaced by a new one from the update.
