Using sent items with remote deployment in multiple domain forests

Scenario:

You have multiple domains in your forest and are experiencing problems with remote deployment – including this error:

The password used for the sent items update service account is incorrect. Please run configuration setup for the sent items update feature.

Reason:

The Sent Items Update registry key requires a change to the Username DWORD.

Solution:

Note: These instructions involve making a change to the Windows Registry. We strongly advise that you complete a backup of the registry before to following these steps. For further information about how to back up and restore the Windows Registry, see Microsoft KB Article 322756: How to back up and restore the registry in Windows, in the Microsoft Knowledge Base.

Close the Exclaimer Signature Manager Exchange Edition console on all servers where it is installed.
On one of the servers, click Start and then Run.
Enter regedit and click OK to open the Registry Editor.
Expand the tree in the left-hand pane and navigate to the path below:

HKLM\Software\Exclaimer Ltd\Mail Disclaimers 1.0\Sent Items Update
The DWORD called Username needs to be changed. The default setting is Domain\username – change this to the user’s UPN ID username@domain (typically, this will be user’s email address).
Export the Sent Items Update registry key (select File > Export).
Copy the exported key file to each server and then import it.
Restart the Exclaimer Signature Manager Exchange Edition Configuration Service.
NOTE: This also restarts the Microsoft Exchange Transport service.
On the next signature update, remote deployment should work normally.
