MORE INFORMATION

Method 1: Use the Ldp.exe Utility

Use the Ldp.exe utility to determine if a particular user is located on an Exchange 2000 server:

1. Start Ldp.exe.
2. Click Connection, and then click Connect.
3. Type the name of a domain controller that hosts the Configuration container, and then click OK.
4. Click Connection, and then click Bind.
5. Type the user name, password, and domain name of an administrative account, and then click OK.
6. Click View, click Tree, leave Base DN blank, and then click OK.
7. In the left pane, expand the following objects:
   • Your Domain
   • Configuration
   • Services
   • Microsoft Exchange
   • Your Organization
   • Administrative Groups
   • Your Administrative Group
   • Servers
   • Your Server
   • InformationStore
   • First Storage Group
   • Mailbox Store (SERVERNAME)
   
   
   
8. In the right pane, scroll to the bottom of the screen to see all the attributes for that mailbox store. Look for the homeMDBBL attribute, which should look similar to the following:

   5> homeMDBBL: CN=John Smith,CN=Users,DC=company,DC=com; CN=Jan Smith,CN=Users,DC=company,DC=com; CN=SystemMailbox{1A5E0095-2AA3-4579-AB26-872B74AA19F0},CN=Microsoft Exchange System Objects,DC=company,DC=com; CN=SMTP (SMITHS16-{1A5E0095-2AA3-4579-AB26-872B74AA19F0}),CN=Connections,CN=Microsoft,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=company,DC=com; CN=Microsoft System Attendant,CN=SMITHS16,CN=Servers,CN=PTAG,CN=Administrative Groups,CN=Microsoft,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=company,DC=com;

   The 5> before the homeMDBBL attribute name indicates that there are five mailboxes on this server. If you look at these individually, you can see the various users that have mailboxes on this server:
   • CN=John Smith,CN=Users,DC=company,DC=com
   • CN=Jan Smith,CN=Users,DC=company,DC=com
   • CN=SystemMailbox{1A5E0095-2AA3-4579-AB26-872B74AA19F0},CN=Microsoft Exchange System Objects,DC=company,DC=com
   • CN=SMTP SMITHS16-{1A5E0095-2AA3-4579-AB26-872B74AA19F0}),CN=Connections,CN=Microsoft,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=company,DC=com
   • CN=Microsoft System Attendant,CN=SMITHS16,CN=Servers,CN=PTAG,CN=Administrative Groups,CN=Microsoft,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=company,DC=com

Method 2: Use Active Directory Users and Computers

1. Open Active Directory Users and Computers on a computer that has Exchange System Manager installed.
2. In the Active Directory Users and Computers console, click View, and then click to select the Advanced Features check box, and then click OK.
3. Click View, and then click Choose Columns.
4. In the Modify Columns box, click Exchange Mailbox Store in the Hidden Columns list, click Add, and then click OK to add the Exchange Mailbox Store to the "Displayed Columns" list.

An "Exchange Mailbox Store" column appears in the Active Directory Users and Computers console, which shows the mailbox store on which a user has a mailbox.
