Change your password using a Web page in case your password expires

Premise of Use: Internal Exchange Server SP3 or Exchange Server SP1 is installed in the company

The following is an example of Exchange Server SP3:

This topic explains how to use Registry Editor to enable the Microsoft Exchange Server 2007 password reset tool.

Microsoft Office Outlook Web Access (OWA) includes a feature that allows users to change their passwords. However, this feature requires users to log on to OWA to change their password. Users cannot log on to the OWA access password change feature when the user's password expires or the user must change their password for the first time they log on. In earlier versions of Microsoft Exchange, administrators could configure the IISADMPWD Web application to help users. To do this, an administrator may direct users whose passwords expire to a webpage that can be accessed anonymously to reset their password. IISADMPWD is not available in Windows Server 2008. Therefore, the password reset feature may not be available to Exchange 2007 users in a Windows Server 2008 environment.

Exchange SP3 adds a new feature to the Client Access server (CAS) role. This feature creates a new Internet information Services (IIS) 7 module that detects expired passwords and redirects users to the new Change Password page. This feature is disabled by default. To enable the password reset feature, you must set the registry key.

To enable the password reset feature

2. Log on to the Exchange server that is running the CAS role by using an account that has local administrator rights.

4. Start Registry Editor, and then locate the following registry subkey:

   Hlkm\system\currentcontrolset\services\msexchange OWA

6. Create the following DWORD value (if it does not already exist):

   Value name:changeexpiredpasswordenabled Value type: REG_DWORD Value data: 1

8. Quit Registry Editor.

Note: When you set changeexpiredpasswordenabled to a value other than 0 (0), the password reset feature is enabled. If this registry value is missing or is set to zero, the password reset feature is disabled.
