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:
- Login to the CAS Server;
- Open the Registry Editor and navigate to HLKMSYSTEMCurrentControlSetservicesMSExchange OWA
- Create a new DWORD (32-bits) and name it ChangeExpiredPasswordEnabled
- Give this DWORD a value 1
- 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.
