Microsoft Exchange Server version 5.5 has a new feature called Item
Recovery, which allows a user to recover deleted items.
If Item Recovery is enabled, when an item is deleted from the client it is
not actually removed from the private or public information store, but only
hidden from view. These deleted items no longer count towards the
mailbox quotas for users. This can cause the size of the information store
databases to grow beyond what was originally planned, depending on the
number of users and the mailbox quotas on each mailbox.
This article explains how you can determine
how much space in the information store is taken up by deleted items
that can be recovered (recoverable items).
Using the Microsoft Exchange Server 5.5 Administrator program, you can determine the number of deleted items on a per user basis
from the Mailbox Resources of the Private Information Store
properties by performing the following steps:
- In the Exchange Server Administrator program, expand Configuration, Servers, and select the Server object.
- To expand the server
object, click the Plus Sign (+) next to server name.
- To expand
the Private Information Store object, click the Plus Sign (+) next to Private Information Store.
- Click the Mailbox Resources object.
- Information on each mailbox is now displayed in the right window
of the Administrator program.
- If the Deleted Items K column is not displayed, on the View
menu, select Columns. The Columns dialog box appears.
- In the Available Columns list, select Deleted Items K, click Add,
and click OK.
- You are now able to see the amount of space used by recoverable
items for each mailbox. Remember that this space does not count toward
the mailbox storage limit.
- To export the Mailbox Resources information to a delimited file:
- Click on the right pane of the Exchange Server Administrator
- On the File menu, select Save Window Contents.
- Type a file name, and click Save.
- The mailbox resources data is saved to the specified file.
The data in the file can then be manipulated using a spreadsheet in any way
you want; for example, you can chart the amount of space used by recoverable
items versus total space used. This gives you information
on whether or not to change the current Item Recovery settings.
The above steps do not provide the total amount of space taken up by
recoverable items in the private or public store. The total amount of space
used by recoverable items can be determined in one of two ways:
