Exchange 2013 - OWA Password Reset

[adamf]

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\Services\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.

 

Any ideas?

I assume you have reset your IIS services by running IISrest in the command prompt.

Yep, done that and it makes no difference.
