This policy setting allows you to configure the amount (by date) of user email Outlook synchronizes locally using Cached Exchange Mode. If you enable this policy setting, you can specify the time-window of email messages that Outlook synchronizes to users' computers. Best photo printer for mac. So what you need to do is leave Outlook's default settings of caching 1 year of mail on the users primary computer but block Outlook caching on shared computers like boardrooms. The problem is that Outlooks cached mode settings in HKeyCurrentUser (HKCU) and you need to apply it only to some computers.

When you create a new profile in Outlook 2003 Cached Exchange mode is enabled by default.
When you upgrade from a previous Outlook version with an Exchange mailbox to Outlook 2003 Cached Exchange mode is disabled by default.
This makes it really hard to determine and control remotely whether your clients have Cached Exchange Mode enabled.
