Deleting end-us
er deleted items on the RISS
Mail items may b
e deleted by the end-user from the Exchange mail store a nd from the RISS in a
coordinated fa
shion. Exchange 2000 and 2003 support a retention interval on end-user deleted items.
If the interva
l were allowed to lapse, the deleted items would be permanently removed (hard deleted)
from the Exchange mail store. To coordinate the deleted items, the delete rule is executed within the
Exchange retention interval.
Location of deleted items
When a mail item is deleted from a user folder, it is m oved to the Deleted Items folder. It remains there
until user action is taken, such as "Empty Deleted Items Folder.” If a m ail item is already in the Deleted
Items folder and the user deletes it a gain, the Exchange retention setting causes the item to move from
the "Deleted Items" folder into the intermediate Dumpster storage. It remains there until either the RISS
delete rule is executed or the Exchange retention interval lapses.
The first decision to make in deleting items is from which location. RISS supports the deletion of items
from the both the "Deleted Items" folder and from the Dumpster. The Dumpster should be c onsidered
a required location. The "Deleted Items" folder is optional and depends on the policy within your
organization. The location selection is made in the Mail At tender rule.
RISS also supports the deletion of Tombstoned and non-Tombstoned mail items. This option is selected
in the RISS Scheduler options for the "Sychronize Deleted Items" rule type. Select the checkbox Delete
non-tombstoned items.
PTDelItems is invoked using a scheduled event created in the miner Scheduler interface. In combination
with the Mail Attender rule, this task performs actions to request repository removal from the specified
RISS document reference. To synchronize the deletion of both RISS and Exchange mail items, you enable
Exchange retention for the target mail store and execute PTDelItems with a rule within the retention period.
Deleted i
tems tag
To provid
e flexibility in processing the deletion of mail items, a tag is a dded to items that fail to delete due
to targeted tombstoning or other conditions. The tag is added as a custom MAPI property, PTDelStatus.
The value of this property is a number that indexes by one for ea ch pass of PTDelItems. When the
PTDelStatus tag exists on a m ail item, it indicates that at tempts have been made to delete the item and
they have failed perhaps due to issues related to RISS retention, or a disabled RISS, or other coordination
issues
. For this reason, the tag can be used in a M ail Attender rule to periodically seach for such items.
Or, the tag can be added to the PTDelItems rule so the same items do not get repeated attempts to delete.
The tag option can be disabled in the RISS.ini configuration file as follows:
[PTDelItems]
TagUnd
eletedItems=False
In a well coordinated system, there will be no items remaining with the PTDelStatus tag.
Configuring deletion re tention
To enable deletion retention on the Exchange server, the following set tings are assigned to each Mailbox
Store. To access the properties page, use Microsoft Exchange System Manager and navigate to each
Exchange server’s mailbox store in each of its storage groups.
