In addition, the following event ID messages may be logged in the Application event log:

Event Type: Error Event Source: MSExchangeIS Event Category: General Event ID: 9519 Date: 5/17/2000 Time: 5:53:44 PM User: N/A Computer: ComputerName Description: Error 0x80004005 starting database "First Storage Group\Mailbox Store (E2K-MSG1)" on the Microsoft Exchange Information Store.
This issue can occur if the default recipient policy specifies any of the following Simple Mail Transfer Protocol (SMTP) address templates:
If a mail-enabled object does not have a given name or surname, the two templates generate the same SMTP address. This behavior causes an error in Lightweight Directory Access Protocol (LDAP) that prevents all proxy addresses from being generated. Therefore, new mailbox stores do not mount because a system mailbox cannot be created.
To resolve this problem, obtain the latest service pack for Microsoft Exchange 2000 Server. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:

To work around this issue, remove the custom SMTP address templates from the default recipient policy, and then create a new recipient policy for these templates.
For example, create a separate recipient policy for SMTP:%firstname.lastname@example.org that uses an LDAP filter such as "(objectclass=user)" or a similar filter that excludes the Configuration objects. When you do so, system mailboxes can be created because they always use the default recipient policy.

Microsoft has confirmed that this is a problem in Microsoft Exchange 2000 Server. This problem was first corrected in Microsoft Exchange 2000 Server Service Pack 2.
The event ID 9546 message may also be caused by multiple system mailboxes.
