Description
You can use this cmdlet on a specific mailbox or all mailboxes in a database. While this task is running, mailbox access is disrupted only for the mailbox that's currently being repaired.
After you begin a repair request, you can't stop it unless you dismount the database.
To avoid performance problems, only one request can be active on a server for a database-level repair, or up to 100 requests can be active on a server for a mailbox-level repair.
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
New-MailboxRepairRequest -Mailbox tony@contoso.com -CorruptionType FolderView
This example detects and repairs all folder views for the mailbox tony@contoso.com.
Example 2
New-MailboxRepairRequest -Mailbox ayla -CorruptionType ProvisionedFolder,SearchFolder -DetectOnly
This example only detects and reports on ProvisionedFolder and SearchFolder corruption issues to Ayla Kol's mailbox. This command doesn't repair the mailbox.
Example 3
New-MailboxRepairRequest -Database MBX-DB01 -CorruptionType AggregateCounts
This example detects and repairs AggregateCounts for all mailboxes on mailbox database MBX-DB01.
Example 4
New-MailboxRepairRequest -Mailbox ayla -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview -Archive
This example detects and repairs all corruption types for Ayla Kol's mailbox and archive.
Example 5
$Mailbox = Get-MailboxStatistics annb
New-MailboxRepairRequest -Database $Mailbox.Database -StoreMailbox $Mailbox.MailboxGuid -CorruptionType ProvisionedFolder,SearchFolder,AggregateCounts,Folderview
This example creates a variable that identifies Ann Beebe's mailbox and then uses the variable to specify the values for the Database and StoreMailbox parameters to create a request to detect and repair all corruption types.
Parameters
-Archive
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The Archive switch specifies whether to repair or detect corruption the archive mailbox that's associated with the specified mailbox. You don't need to specify a value with this switch.
If you don't use this switch, only the primary mailbox is included.
You can't use this switch with the Database parameter.
Parameter properties
| Type: | SwitchParameter |
| Default value: | None |
| Supports wildcards: | False |
| DontShow: | False |
Parameter sets
Mailbox
| Position: | Named |
| Mandatory: | False |
| Value from pipeline: | False |
| Value from pipeline by property name: | False |
| Value from remaining arguments: | False |
-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false. - Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a built-in pause. For these cmdlets, specifying the Confirm switch without a value introduces a pause that forces you acknowledge the command before proceeding.
