Exchange 2013 - OWA Password Reset
We've got an Exchange 2013 which we are slowly migrating mailboxes to (from Exchange 2010) and we keep running into a problem where if we set a password to be changed at logon or it's expired the user cannot logon.
We have a registry entry HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSExchange OWA\ChangeExpiredPasswordEnabled set to 1 on the CAS server but it doesn't work.
The registry key was set at install I think (as I don't remember setting it) and a couple of weeks ago I saw it work, where I was prompted to change the password, now it's stopped again...
I don't know why it keeps stopping, but as we plan to complete our migration to 2013 over the summer I need to get to the bottom of it.
