So i upgraded our exchange servers from 2003 to 2010 this week-end, i created the new Listener that uses FBA and created rules for OWA, ActiveSync, Outlook Anywhere and finally Legacy.
The OWA access works fine and redirection to legacy server for 2003 users is working flawlessly except that now the change password feature in webmail 2003 does not work anymore (i am not talking about the change password feature on TMG itself with FBA) but the one with exchange (Virtual Directory called Iisadmpwd)
The error i receive is:
Error Code: 403 Forbidden. The server denied the specified Uniform Resource Locator (URL). Contact the server administrator. (12202)
Do you know if there is anything i need to change on IIS server or TMG?
