Password Reset Tool and UPN

With Exchange Server 2010 SP1 there’s the possibility to change your password using OWA when it expires. When a user’s password is changed and the “User must change password at next logon” is set you can easily test this.

Follow these steps to enable the password reset tool:

  1. Login to the CAS Server;
  2. Open the Registry Editor and navigate to HLKMSYSTEMCurrentControlSetservicesMSExchange OWA
  3. Create a new DWORD (32-bits) and name it ChangeExpiredPasswordEnabled
  4. Give this DWORD a value 1
  5. Restart the Internet Information Server using IISRESET

In the original version it was only possible to logon with a “domainusername” option. With Rollup Update 3 V3 for Exchange Server 2010 SP1 it is also possible to use a UPN style (username@domain.com) logon.
