Outlook Web Access

Disable the Change Password Button

Users can change their Windows 2000 passwords remotely by using Outlook Web Access (this feature is available on the Options page and requires administrative setup on the Exchange server). Some organizations may want to disable this feature so that users can only change their passwords while inside the firewalls. The following registry key on the computer running Exchange Server, when set to 1, will hide the Change Password button on users' Option pages.

Warning    Using Registry Editor incorrectly can cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it, and you should also update your Emergency Repair Disk (ERD).

To prevent users from changing their passwords:

  1. On the Start menu, click Run, type Regedt32.exe, and then click OK.
  2. In Registry Editor, under HKEY_LOCAL_MACHINE on Local Machine, go to SYSTEM\CurrentControlSet\Services\MSExchangeWEB\OWA.
  3. On the Edit menu, select Add Value.
  4. In Add Value, type DisablePassword as the value name, select REG_DWORD as the data type, and then click OK.
  5. In DWORD Editor, type 1 in the Data field . To enable the Change Password button, type 0.
