SYMPTOMS
A feature has been added to ensure that deleted data is removed from .pst and .ost files. This feature is activated through a registry entry. When it is enabled, deleted data is overwritten when Outlook is shut down. Most data is removed and overwritten during normal operation, but a small percentage can remain if this feature is not activated.
RESOLUTION
A supported feature that modifies the product's default behavior is now available from Microsoft, but it is only intended to modify the behavior that this article describes. Apply it only to systems that specifically require it. This feature may receive additional testing. Therefore, if the system is not severely affected by the lack of this feature, we recommend that you wait for the next Outlook 2000 Service Update that contains this feature.
To obtain this feature immediately, contact Microsoft Product Support Services. For a complete list of Microsoft Product Support Services telephone numbers and information about support costs, visit the following Microsoft Web site:
