Exchange 2007 OWA "change password" doesn't reflect active directory username change.

Hi, we're going through a naming policy change and are having to change all of our users active directory usernames. However, it's been noticed that some (not all) changes are not reflecting in the "Change Password" option within OWA. The username remains as the original despite it being changed in AD and the Exchange Management Console alias.

What am i missing?!!

Thank you to anyone who can help...

what you are seeing is the users' alias, have you changed it

The display name and or the User logon name pre windows 2000 under the account Tab.

The alias has been changed on both Exchange servers and the username has been changed on both instances of the account tab in AD.

It's like the client access exchange server is caching the usernames somewhere but looking on the account tab within the exchange console it's showing the correct (updated) username.
Check their Exchange alias which is separate from their Active Directory usernames:

In the Exchange Management Console > expand Recipient ConfigurationMailbox > right click on a user's mailbox > Properties > at the bottom of the General tab will be an Alias field.

Is this what you're seeing in OWA?

VB ITS - unfortunately the alias is already set to the new username. I tried changing it, applying and then changing it back to the new name but still no joy I'm afraid.

A bit more info - we have 2 exchange servers, one internal facing and one external facing. It's the external one that hosts OWA. Both are sync'd, so changes made on one are reflected on the other.

It's like the old name is being cached. And I've tried deleting all temp internet files!
Strange indeed. Could it be perhaps AD replication if you have multiple DCs?

I did think that too but because the Account tab within the Exchange Management Console shows the updated usernames I'm not so sure. I've also logged on to each DC and have checked they've all replicated correctly.

When the user logs on to the network he uses his new username fine. It's only when he comes to reset his password through OWA the problem exists.

IT WORKED! Thank you VB ITS. Really appreciate your help.
Great! Just to clarify, which solution was it that resolved the issue? Restarting the Exchange AD Toplogy Service or disabling the local SID cache?

Apologies, it was disabling the local SID cache that did the trick.
