I'm using Exchange 2010 SP1 and have enabled expired password handling for OWA using the steps described at http://technet.microsoft.com/en-us/library/bb684904.aspx. OWA now correctly brings up a window to allow users with expired passwords to change it. However, our support group is wondering if it is possible to customize some of the text that appears in this window. For example, when an expired password is encountered OWA displays the text 'Your password has expired and you need to change it before you sign in to Outlook Web App'. They would like to include a link or some text that explains our password complexity rules. I'm guessing it's possible, but I have no idea as to where this text would be stored/modified. Any help would be greatly appreciated.
