XADM: Private Information Store Has High Disk Size Item Numbers |
The information in this article applies to:
-
Microsoft Exchange Server, version 5.5
SYMPTOMS
When you select an Exchange Server, version 5.5, in the left pane of the
Microsoft Exchange Administrator program, get properties on the private
information store, and select the Mailbox Resources tab, you may see
exceptionally high disk space size occupied by unfamiliar mailbox names.
For example, a mailbox called Admin or Internet Mail Service may occupy a
disk space of 40,967 KB with 520 items. When you check the Internet Mail
Service queues, you find them empty or with very few items.
CAUSE
The Internet Mail Service uses MAPI much as the user clients do to deliver
and receive messages into the information store. Exchange creates seven
mailboxes when it is started; one of them is for the Internet Mail Service.
These mailboxes are not valid users' mailboxes, and you cannot create a
profile or log on as one of those mailboxes. These mailboxes are for
regular message transactions.
Exchange Server version 5.5 has optimized the way the information store
works with the connectors and gateways, through the use of these mailboxes.
The Exchange Administrator program, however, no longer keeps accurate
counters for such mailboxes. These numbers are meaningless and should be
ignored.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 5.5.
This problem has been corrected in the latest U.S. Service Pack for
Microsoft Exchange Server version 5.5. For information about obtaining the
Service Pack, query on the following word in the Microsoft Knowledge Base

MORE INFORMATION
After you apply the fix, the information store attempts to determine
whether each mailbox listed on the Mailbox Resources tab is a connector
mailbox. If the information store is able to determine that a mailbox is a
connector mailbox, it lists a 0 (zero) in the Total K and Total No. Items
columns for that mailbox.
Connector mailboxes are mailboxes used by connectors to send and receive
messages. The following Exchange Server 5.5 connectors use this type of
mailbox to send and receive messages:
- Connector for Lotus cc:Mail
- Internet Mail Service
- Notes Connector, SNADS Connector, and PROFS Connector
Some other Exchange Server connectors send and receive messages by
communicating directly with the message transfer agent (MTA). These
connectors include the X.400 Connector and the Microsoft Mail Connector.
For information about a similar problem in which the Mailbox Resources tab
reports information that appears inaccurate, please see the following
article in the Microsoft Knowledge Base:
Q152458
XADM: Mailbox Resources Reporting Usage Not Seen by Client
On rare occasions, disk space counters for regular users, other than these
seven mailboxes, may also become inaccurate. An example is when the
Exchange Server computer crashes. If this happens, run the ISINTEG utility
to fix these counters.
