On examining the C:\Program Files\Windows Small Business Server\Logs\adduser.log, you would see something similar:

[600] 110124.182639.8611: Messaging: Executed management shell command: get-MailboxDatabase
[600] 110124.182639.8954: Messaging: End Microsoft.WindowsServerSolutions.Messaging.Management.MessagingRunspace.StaticExecute
[600] 110124.182639.9013: Messaging: MessagingTaskException: Unable to find default mailbox database with name [] - Check access and verify if mailbox database exists - Error# (80004)
[600] 110124.182639.9170: AdminTME: Status: TaskId = MessagingTasks.TaskCreateMailbox, RootTaskId = TaskCreateUser, Success: True, Warning: True, Continue: True, Message: Unable to find default mailbox database. Make sure mailbox database exists and you have access to view the database.

CAUSE

This issue can occur if the 'Add a New User' wizard is unable to retrieve the mailbox database name. For this purpose, it looks for the registry key MailboxDatabaseName under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Messaging.

RESOLUTION

To resolve this issue, follow these steps:

1.) Launch Exchange Management Shell from an elevated prompt and execute the following command:

Get-MailboxDatabase

2.) Make a note of the database name listed under the Name column as shown in the example below. You would require this information in the later steps.

3.) Open Registry Editor

4.) Expand HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Messaging\

5.) Create a new String value as follows:

Type: REG_SZ
 
Name: MailboxDatabaseName
 
Value: The database name you obtained from Step 2 above

6.) Close Registry Editor
