Use the Set-MailboxRestoreRequest cmdlet to change restore request options after the request has been created. You can use this cmdlet to recover from failed restore requests.

For information about the parameter sets in the Syntax section below, see Syntax.

Syntax

Set-MailboxRestoreRequest [-AcceptLargeDataLoss <SwitchParameter>] [-BadItemLimit <Unlimited>] [-BatchName <String>] [-CompletedRequestAgeLimit <Unlimited>] [-LargeItemLimit <Unlimited>] [-Priority <Lowest | Lower | Low | Normal | High | Higher | Highest | Emergency>] [-SkipMerging <SkippableMergeComponent[]>] <COMMON PARAMETERS>
Set-MailboxRestoreRequest -RehomeRequest <SwitchParameter> <COMMON PARAMETERS>
COMMON PARAMETERS: -Identity <MailboxRestoreRequestIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

Examples

EXAMPLE 1

This example changes the second restore request for Ayla\MailboxRestore1 to skip 10 corrupt mailbox items.

Copy Code 
Set-MailboxRestoreRequest -Identity "Ayla\MailboxRestore1" -BadItemLimit 10

EXAMPLE 2

This example changes the first restore request for Kweku's mailbox to skip 100 corrupt items. Because the BadItemLimit is greater than 50, the AcceptLargeDataLoss parameter must be specified.

Copy Code 
Set-MailboxRestoreRequest -Identity "Kweku\MailboxRestore" -BadItemLimit 100 -AcceptLargeDataLoss

Detailed Description

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 restore request" entry in the Recipients Permissions topic.

Parameters

Parameter Required Type Description

Identity

Required

Microsoft.Exchange.Management.RecipientTasks.MailboxRestoreRequestIdParameter

The Identity parameter specifies the identity of the restore request. The Identity parameter consists of the alias of the mailbox to be restored and the name that was specified when the restore request was created. The identity of the restore request uses the following syntax: <alias>\<name>.

If you didn't specify a name for the restore request when it was created, Exchange automatically generated the default name MailboxRestore. Exchange generates up to 10 names, starting with MailboxRestore and then MailboxRestoreX (where X = 1–9).

RehomeRequest

Required

System.Management.Automation.SwitchParameter

The RehomeRequest switch specifies that the mailbox restore request be moved to a different mailbox database. Use this parameter to edit a mailbox restore request in the case where the source mailbox database from the original move request has to be removed.

AcceptLargeDataLoss

Optional

System.Management.Automation.SwitchParameter

The AcceptLargeDataLoss parameter specifies that a large amount of data loss is acceptable if the BadItemLimit is set to 51 or higher. Items are considered corrupted if the item can't be read from the source database or can't be written to the target database. Corrupted items won't be available in the destination mailbox or .pst file.

BadItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The BadItemLimit parameter specifies the number of bad items to skip if the request encounters corruption in the mailbox. Use 0 to not skip bad items. The valid input range for this parameter is from 0 through 2147483647. The default value is 0. We recommend that you keep the default value 0 and only change the BadItemLimit parameter value if the request fails.

Note:
If you set the BadItemLimit parameter to more than 50, the command fails, and you receive a warning stating: "Please confirm your intention to accept a large amount of data loss by specifying AcceptLargeDataLoss." If you receive this warning, you need to run the command again, this time using the AcceptLargeDataLoss parameter. No further warnings appear, and any corrupted items aren't available after the process is complete.

BatchName

Optional

System.String

The BatchName parameter specifies the name of the batch. Use this parameter to change, create, or remove a batch name.

To remove a batch name, set the BatchName parameter value to an empty string or to null, for example, -BatchName "" or -BatchName $null.

CompletedRequestAgeLimit

Optional

Microsoft.Exchange.Data.Unlimited

The CompletedRequestAgeLimit parameter specifies how long the status of a completed restore request is set to Completed. If this parameter is set to a value of 0, the status is cleared immediately instead of changing it to Completed.

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.

LargeItemLimit

Optional

Microsoft.Exchange.Data.Unlimited

The LargeItemLimit parameter specifies the number of items to skip in the mailbox because these items exceed the item size limit in the target mailbox data. Use 0 to not skip any large items.

Note:
If you set the LargeItemLimit parameter to 51 or higher, you must also include the AcceptLargeDataLoss parameter.

Priority

Optional

Microsoft.Exchange.MailboxReplicationService.RequestPriority

The Priority parameter specifies the priority of the mailbox restore request. Use one of the following values:

  • Emergency

  • Highest

  • Higher

  • High

  • Normal

  • Low

  • Lower

  • Lowest

SkipMerging

Optional

Microsoft.Exchange.Management.RecipientTasks.SkippableMergeComponent[]

The SkipMerging parameter specifies folder-related items to skip when restoring the mailbox. Use one of the following values:

  • FolderRules

  • FolderACLs

  • InitialConnectionValidation

Use this parameter only if a restore request fails because of folder rules, folder access control lists (ACLs), or initial connection validation.

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.
