Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.
Note This registry value must be enabled on both front-end and back-end servers.
For Exchange 2000 Server and for Exchange Server 2003, you can use the registry to show or hide the Change Password button. To do this, follow these steps.
1. Start Registry Editor, and then locate the following registry key:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeWeb
2. If an OWA key is not present under MSExchangeWeb, click the Edit menu, click New, and then click Key to add a new key named OWA.
3. Locate the DisablePassword value and change the data to "0." If this value is not present, click the Edit menu, click New, click DWORD_Value to add the following value to the OWA registry subkey if you want the Change Password button to appear:
Value name: DisablePassword
Value type: REG_DWORD
Data: 0
If you want to hide the Change Password button, change the DisablePassword value data to "1."
4. Stop and then restart the Exchange Information Store Service and the IIS Admin Service. This stops and restarts the World Wide Web Publishing Services (W3SVC). In an Exchange 2000 Server environment, restarting the IIS Admin Service restarts the Microsoft Exchange System Attendant and the Microsoft Exchange Information Store.
5. Make sure that you all the dependent services that you require are restarted, such as IMAP4, POP3, Microsoft Exchange Routing Engine, W3SVC, MTA Stacks.
