Use the Clean-MailboxDatabase cmdlet to scan Active Directory for disconnected mailboxes that aren't yet marked as disconnected in the Microsoft Exchange store and update the status of those mailboxes in the Exchange store. This cmdlet isn't able to update the Exchange store unless the Microsoft Exchange Information Store service is running and the database is mounted.
Syntax
clean-MailboxDatabase -Identity
<DatabaseIdParameter> [-Confirm [<SwitchParameter>]]
[-DomainController <Fqdn>] [-WhatIf
[<SwitchParameter>]]

Detailed Description
A connected mailbox has two parts: the mailbox object in the Exchange store and the user object with Exchange properties in Active Directory. A disconnected mailbox is the mailbox object in the Exchange store, but it isn't connected to a user object in Active Directory. To disconnect a mailbox, use the Disable-Mailbox cmdlet. To disconnect a mailbox and remove the user object from Active Directory, use the Remove-Mailbox cmdlet. If you want to permanently remove a mailbox object from the Exchange store, use the Remove-Mailbox cmdlet.
If you want to reconnect a disconnected mailbox to an Active Directory user account, use the Connect-Mailbox cmdlet.
Under normal circumstances, it isn't necessary to run the Clean-MailboxDatabase cmdlet because a mailbox is marked as disconnected immediately after the Disable-Mailbox or Remove-Mailbox command completes. If you used the Disable-Mailbox cmdlet or the Remove-Mailbox cmdlet while the Microsoft Exchange Information Store service was stopped, or if a mailbox was disabled by an external means other than the Disable-Mailbox cmdlet or Remove-Mailbox cmdlet, you may want to use the Clean-MailboxDatabase cmdlet to scan for disconnected mailboxes.
You need to be assigned permissions before you can run this cmdlet. Although all parameters for this cmdlet are listed in this topic, you may not have access to some parameters if they're not included in the permissions assigned to you. To see what permissions you need, see the "Mailbox Database permissions" entry in the Mailbox Permissions topic.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
|
Identity |
Required |
Microsoft.Exchange.Configuration.Tasks.DatabaseIdParameter |
The Identity parameter specifies the mailbox database that you want to update. You can use one of the following values:
|
|
Confirm |
Optional |
System.Management.Automation.SwitchParameter |
The Confirm switch causes the command to pause processing and requires you to acknowledge what the command will do before processing continues. You don't have to specify a value with the Confirm switch. |
|
DomainController |
Optional |
Microsoft.Exchange.Data.Fqdn |
The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory. The DomainController parameter isn't supported on the Edge Transport server role. The Edge Transport server role writes only to the Active Directory Lightweight Directory Services (AD LDS) instance. |
|
WhatIf |
Optional |
System.Management.Automation.SwitchParameter |
The WhatIf switch instructs the command to simulate the actions that it would take on the object. By using the WhatIf switch, you can view what changes would occur without having to apply any of those changes. You don't have to specify a value with the WhatIf switch. |
