Topic Last Modified: 2014-07-03

This cmdlet is available only in on-premises Exchange Server 2013.

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

This cmdlet is available only in the Mailbox Import Export role, and by default, that role isn't assigned to a role group. To use this cmdlet, you need to add the Mailbox Import Export role to a role group (for example, to the Organization Management role group). For more information, see the "Add a role to a role group" section in Manage role groups.

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

Set-MailboxExportRequest [-AcceptLargeDataLoss <SwitchParameter>] [-BadItemLimit <Unlimited>] [-BatchName <String>] [-CompletedRequestAgeLimit <Unlimited>] [-InternalFlags <InternalMrsFlag[]>] [-LargeItemLimit <Unlimited>] [-Priority <Lowest | Lower | Low | Normal | High | Higher | Highest | Emergency>] [-SkipMerging <SkippableMergeComponent[]>] <COMMON PARAMETERS>

Set-MailboxExportRequest -RehomeRequest <SwitchParameter> <COMMON PARAMETERS>

COMMON PARAMETERS: -Identity <MailboxExportRequestIdParameter> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-WhatIf [<SwitchParameter>]]

This example changes the second export request Ayla\MailboxExport1 to accept up to 10 corrupt mailbox items.

Set-MailboxExportRequest -Identity "Ayla\MailboxExport1\" -BadItemLimit 10

You can pipeline the Set-MailboxExportRequest cmdlet from the Get-MailboxExportRequest cmdlet.

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 "Import Export" entry in the Recipients Permissions topic.


Parameter Required Type Description




The Identity parameter specifies the identity of the export request. By default, export requests are named <alias>\MailboxExportX (where X = 0–9). If you specify a name for the export request, use the following syntax: <alias>\<name>.




The RehomeRequest parameter specifies to the Microsoft Exchange Mailbox Replication service (MRS) that the request needs to be moved to the same database as the mailbox that's being exported. This parameter is used primarily for debugging purposes.




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.




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.

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.




The BatchName parameter specifies the name of the batch.




The CompletedRequestAgeLimit parameter specifies how long the request will be kept after it has completed before being automatically removed. The default value is 30 days.




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.




The DomainController parameter specifies the fully qualified domain name (FQDN) of the domain controller that writes this configuration change to Active Directory.




The InternalFlags parameter specifies the optional steps in the request. This parameter is used primarily for debugging purposes.




The LargeItemLimit parameter specifies the number of large items to skip if the request encounters such items in the mailbox. Use 0 to not skip any large items. If any number above 50 is specified, the AcceptLargeDataLoss parameter must also be specified. The default value is 0. We recommend that you use the default value of 0 and increase the LargeItemLimit only when large items are encountered.




The Priority parameter specifies the order in which this request is processed in the request queue. Requests are processed in order, based on server health, status, priority, and last update time.




The SkipMerging parameter specifies steps in the export that should be skipped. This parameter is used primarily for debugging purposes.




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.
