How to enable Cache mode on Outlook 2007 SP2 for shared mailbxoes

Since the introduction of Cached mode in Outlook, we've seen issues with users not understanding why additional mailbox access was so slow. Personal mailboxes were cached but unfortunately it was not possible to cache the additional mailboxes, resulting in a confusing experience for end-users.
There already was an Outlook 2007 post-SP1 update (KB 957909) which made caching of additional mailboxes possible, but since the introduction of Office 2007 SP2 it makes more sense to just upgrade Office 2007 to SP2.

To enable this feature, open up registry editor, navigate to to
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\Cached Mode
HKEY_CURRENT_USER\Software\Policies\Microsoft\Office\12.0\Outlook\Cached Mode,

add a DWORD value named CacheOthersMail and assign it the value of "1".
Next, disable "header downloads":
In Outlook select File and then click Cached Exchange Mode. Clear the following options when enabled: Download Headers and then Full Items, Download Headers, On Slow Connections Download Only Header.
