If you've deployed Exchange Server 2003 Outlook Web Access (OWA), you may have noticed that it no longer displays the Change Password button by default. This is a change from Exchange 2000, where the default installation displayed the Change Password button.
If you've deployed Secure Sockets Layer (SSL) and want your users to be able to change their passwords from OWA, you can get that button back with a quick registry edit.
Follow these steps:
Value name: DisablePassword
The data value of 0 tells Exchange to display the Change Password button in OWA; a data value of 1 hides the Change Password button. You can also use this registry edit in Exchange 2000 if you want to hide the Change Password button.
After editing the registry, restart your Exchange services for the change to take effect. If OWA is on a front-end/back-end implementation, you must make the registry changes to both the front-end and back-end servers.
Note: Editing the registry is risky, so be sure you have a verified backup before making any changes.
