Disable shared mail folder caching

This policy setting allows you to control the caching of shared mail folders.

If you enable this policy setting, Outlook will only cache shared non-mail folders.

If you disable or do not configure this policy setting, shared mail and non-mail folders you have access to are cached in your .ost file when you add another mailbox to your profile.

Supported on: At least Windows 7
