Procedures for mailbox imports from .pst files in Exchange Server

Mailbox import requests use the Microsoft Exchange Mailbox Replication service (MRS) to import the contents of .pst files into mailboxes. For more information, see Mailbox imports and exports in Exchange Server.

This topic shows you how to:

  • Create mailbox import requests

  • View mailbox import requests.

  • Modify mailbox import requests that haven't completed.

  • Suspend mailbox import requests that haven't completed or failed.

  • Resume suspended or failed mailbox import requests

  • Remove mailbox import requests.

What do you need to know before you begin?

Important

The procedures in this topic require the Mailbox Import Export role, which isn't assigned to any role groups by default. To assign the role to a role group that you belong to, see Add a role to a role group. Note that changes in permission require you to log off and log on for the changes to take effect.

  • Estimated time to complete each procedure: 5 minutes

  • You need to import the .pst files from a UNC network share (\ <Server>\ <Share>\ or \ <LocalServerName>\c$). The Exchange Trusted Subsystem security group requires the Read permission to the network share. If the share doesn't have this permission, you'll get errors when you try to import .pst files to mailboxes.

  • You can create mailbox import requests in the Exchange admin center (EAC) or in the Exchange Management Shell. All other procedures can only be done in the Exchange Management Shell. For more information about accessing and using the EAC, see Exchange admin center in Exchange Server. To learn how to open the Exchange Management Shell in your on-premises Exchange organization, see Open the Exchange Management Shell.

  • For information about keyboard shortcuts that may apply to the procedures in this topic, see Keyboard shortcuts in the Exchange admin center.

Create mailbox import requests

Use the EAC to create a mailbox import request

  1. In the EAC, go to Recipients > Mailboxes > click More options More Options icon, and select Import PST.

    In the EAC, select Recipients, Mailboxes, and then select More Options.

  2. The Import from a .pst wizard opens. On the first page, enter the UNC path and filename of the source .pst file.

    In the Import from a .pst file wizard in the EAC, specify the source .pst file.

    When you're finished, click Next.

  3. On the next page, select the target mailbox, and then select one of these options:

    • Import to this mailbox

    • Import to this mailbox's archive

    In the Import from a .pst file wizard in the EAC, select the target mailbox (primary or archive).

    When you're finished, click Next.

  4. On the last page, configure one of these settings:

    • Leave the Send email to the mailbox below when the .pst file has been exported check box selected. Click Browse to add or remove notification recipients.

    • Clear the Send email to the mailbox below when the .pst file has been exported check box.

    In the Import from a .pst file wizard in the EAC, select whether to receive notification messages.

    When you're finished, click Finish.

Use the Exchange Management Shell to create a mailbox import request

To create a mailbox import request, use this syntax:

New-MailboxImportRequest  [-Name <UniqueName>] -FilePath <UNCPathToPST> -Mailbox <TargetMailboxIdentity> [-IsArchive] [-SourceRootFolder <PSTFolder>] [-TargetRootFolder <MailboxFolder>] [-IncludeFolders <MailboxFolder1>,<MailboxFolder2>...] [-ExcludeFolders <MailboxFolder1>,<MailboxFolder2>...] [-Priority <PriorityValue>]

This example creates a new mailbox import request with these settings:

  • Mailbox import request name: The default value MailboxImport is used, because we aren't using the Name parameter. The unique identity of the mailbox import request is <MailboxIdentity>\MailboxImportX (X is either not present, or has the value 0 to 9).

  • Source .pst file: \\SERVER01\PSTFiles\Archives\Vbarrios.pst

  • Target mailbox: Valeria Barrios

  • Content and folders: Content in all folder paths in the .pst file is replicated in the target mailbox. Content is merged under existing folders and new folders are created if they don't already exist.

  • Priority: Normal, because we aren't using the Priority parameter.

New-MailboxImportRequest -FilePath \\SERVER01\PSTFiles\Archives\Vbarrios.pst -Mailbox "Valeria Barrios"

This example creates a new mailbox import request with these settings:

  • Mailbox import request name: The custom name Kathleen Reiter Import is specified by the Name parameter. Specifying a custom name allows more than 10 mailbox import requests for the mailbox. The unique identity value of the mailbox import request is <MailboxIdentity>\<MailboxImportRequestName> (for example, kreiter\Kathleen Reiter Import).

  • Source .pst file: \\SERVER01\PSTFiles\Archives\Recovered.pst

  • Target mailbox: The archive mailbox for Kathleen Reiter (Kathleen's primary mailbox alias is kreiter).

  • Content and folders: Only content in the Inbox folder of the .pst file is imported (regardless of the localized name of the folder), and it's imported to the Recovered Files folder in the target mailbox.

  • Priority: High

New-MailboxImportRequest -Name "Kathleen Reiter Import" -FilePath \\SERVER01\PSTFiles\Recovered.pst -Mailbox kreiter -IsArchive -IncludeFolders "#Inbox#" -TargetRootFolder "Recovered Files" -Priority High

For detailed syntax and parameter information, see New-MailboxImportRequest.

How do you know this worked?

To verify that you've successfully created a mailbox import request, do any of these steps:

  • In the EAC, click the notification viewer Notifications icon to view the status of the request.

  • If you created the mailbox import request in the EAC, and selected the option to send notification email messages, check the notification messages. The sender is Microsoft Exchange. The first message has the subject Your Import PST request has been received. If the import request completed successfully, you'll receive another message with the subject Import PST has finished.

  • Replace <MailboxIdentity> with the name, email address, or alias of the target mailbox, and run this command in the Exchange Management Shell to verify the basic property values:

    Get-MailboxImportRequest -Mailbox "<MailboxIdentity>" | Format-List Name,FilePath,Mailbox,Status
    
  • Replace <MailboxIdentity> and <MailboxImportRequestName> with the appropriate values, and run this command in the Exchange Management Shell to verify the details:

    Get-MailboxImportRequestStatistics -Identity "<MailboxIdentity>\<MailboxImportRequestName>"
    

Use the Exchange Management Shell to view mailbox import requests

By default, the Get-MailboxImportRequest cmdlet returns the name, target mailbox, and status of mailbox import requests. If you pipeline the command to the Format-List cmdlet, you'll only get a limited number of additional useful details:

  • FilePath: The source .pst file.

  • RequestGUID: The unique GUID value of the mailbox import request.

  • RequestQueue: The mailbox database that the import request is being run on.

  • BatchName: The optional batch name for the mailbox import request.

  • Identity: The unique identity value of the mailbox import request (<MailboxIdentity>\ <MailboxImportRequestName>).

By default, the Get-MailboxImportRequestStatistics cmdlet returns the name, status, alias of the target mailbox, and the completion percentage of mailbox import requests. If you pipeline the command to the Format-List cmdlet, you'll see detailed information about the mailbox import request.

This example returns the summary list of all mailbox import requests.

Get-MailboxImportRequest

This example returns additional information for mailbox import requests to the mailbox Akia Al-Zuhairi.

Get-MailboxImportRequest -Mailbox "Akia Al-Zuhairi" | Format-List

This example returns the summary list of in-progress mailbox import requests for mailboxes that reside on the mailbox database named DB01.

Get-MailboxImportRequest -Status InProgress -Database DB01

This example returns the summary list of completed mailbox import requests in the batch named Import DB01 PSTs.

Get-MailboxImportRequest -Status Completed -BatchName "Import DB01 PSTs"

For detailed syntax and parameter information, see Get-MailboxImportRequest.

To view detailed information about a mailbox import request, use this syntax:

Get-MailboxImportRequestStatistics -Identity <MailboxImportRequestIdentity> [-IncludeReport] | Format-List

Where <MailboxImportRequestIdentity> is the identity value of the mailbox import request (<MailboxIdentity>\ <MailboxImportRequestName> or <RequestGUID>).

This example returns detailed information for the mailbox import request named MailboxImport for Akia Al-Zuhairi's mailbox, including the log of actions in the Report property.

Get-MailboxImportRequestStatistics -Identity "aal-zuhairi\MailboxImport" -IncludeReport | Format-List

For detailed syntax and parameter information, see Get-MailboxImportRequestStatistics.

Use the Exchange Management Shell to modify mailbox import requests

You can modify mailbox import requests that haven't completed. You can't modify the fundamental settings of an existing request (for example, the source .pst file, target mailbox, the source content in the .pst file, or the destination in the target mailbox).

To modify a mailbox import request, use this syntax:

Set-MailboxImportRequest -Identity <MailboxIdentity>\<MailboxImportRequestName> [-BadItemLimit <value>] [-LargeItemLimit <value>] [-AcceptLargeDataLoss]

This example modifies the failed mailbox import request for the mailbox of Valeria Barrios to accept up to five corrupted mailbox items.

Set-MailboxImportRequest -Identity "Valeria Barrios\MailboxImport" -BadItemLimit 5

For detailed syntax and parameter information, see Set-MailboxImportRequest.

Note: After you modify a suspended or failed mailbox import request, you need to resume it by using the Resume-MailboxImportRequest cmdlet.

How do you know this worked?

To verify that you've successfully modified a mailbox import request, replace <MailboxIdentity> and <MailboxImportRequestName> with the appropriate values, and run this command in the Exchange Management Shell to verify the details:

Get-MailboxImportRequestStatistics -Identity "<MailboxIdentity>\<MailboxImportRequestName>" | Format-List

Use the Exchange Management Shell to suspend mailbox import requests

You can suspend mailbox import requests that are in progress. You can't suspend completed or failed mailbox import requests.

To suspend a mailbox import request, use this syntax:

Suspend-MailboxImportRequest -Identity <MailboxIdentity>\<MailboxImportRequestName> [-SuspendComment "<Descriptive Comment>"]

This example suspends the mailbox import request to Kathleen Reiter's mailbox that's named Kathleen Reiter Import.

Suspend-MailboxImportRequest -Identity "kreiter@contoso.com\Kathleen Reiter Import"

This example suspends all in-progress mailbox import requests with the comment "OK to resume after 10 P.M. on Monday 6/19"

Get-MailboxImportRequest -Status InProgress | Suspend-MailboxImportRequest -SuspendComment "OK to resume after 10 P.M. on Monday 6/19"

For detailed syntax and parameter information, see Suspend-MailboxImportRequest.

Notes:

  • You can also use the New-MailboxImportRequest cmdlet with the Suspend switch to create a suspended mailbox import request.

  • You use the Resume-MailboxImportRequest parameter to resume suspended mailbox import requests.

How do you know this worked?

To verify that you've successfully suspended a mailbox import request, do any of these steps:

  • Replace <MailboxIdentity> with the name, email address, or alias of the target mailbox, run this command in the Exchange Management Shell, and verify that the Status property has the value Suspended:

    Get-MailboxImportRequest -Mailbox "<MailboxIdentity>" | Format-List Name,FilePath,Mailbox,Status
    
  • Run this command in the Exchange Management Shell, and verify that the suspended mailbox import request is listed:

    Get-MailboxImportRequest -Status Suspended
    

Use the Exchange Management Shell to resume mailbox import requests

You can resume suspended or failed mailbox import requests.

To resume a mailbox import request, use this syntax:

Resume-MailboxImportRequest -Identity <MailboxIdentity>\<MailboxImportRequestName>

This example resumes the failed mailbox import request for Valeria Barrios' mailbox.

Resume-MailboxImportRequest -Identity vbarrios\MailboxImport

This example resumes all suspended mailbox import requests.

Get-MailboxImportRequest -Status Suspended | Resume-MailboxImportRequest

For detailed syntax and parameter information, see Resume-MailboxImportRequest.

How do you know this worked?

To verify that you've successfully resumed a mailbox import request, replace <MailboxIdentity> with the name, email address, or alias of the target mailbox, run this command in the Exchange Management Shell, and verify that the Status property doesn't have the value Suspended:

Get-MailboxImportRequest -Mailbox <MailboxIdentity> | Format-List Name,FilePath,Mailbox,Status

Use the Exchange Management Shell to remove mailbox import requests

You can remove fully or partially completed mailbox import requests.

  • If you remove a partially completed mailbox import request, the request is removed from the MRS job queue. Any content that's already been imported from the .pst file isn't removed from the target mailbox.

  • By default, completed mailbox import request are removed after 30 days (you can override this value with the CompletedRequestAgeLimit parameter), and failed requests aren't automatically removed. But, if you use the RequestExpiryInterval parameter when you create or modify a mailbox import request, these results are available:

    • RequestExpiryInterval with a timespan value: Completed and failed requests are automatically removed after the specified timespan.

    • RequestExpiryInterval with the value unlimited: Completed and failed requests aren't automatically removed.

This example removes the mailbox import request named MailboxImport for Akia Al-Zuhairi's mailbox.

Remove-MailboxImportRequest -Identity "aal-zuhairi\MailboxImport"

This example removes all completed mailbox import requests.

Get-MailboxImportRequest -Status Completed | Remove-MailboxImportRequest

For detailed syntax and parameter information, see Remove-MailboxImportRequest.

How do you know this worked?

To verify that you've successfully removed a mailbox import request, replace <MailboxIdentity> with the name, email address, or alias of the target mailbox, run this command in the Exchange Management Shell, and verify that the mailbox import request isn't listed:

Get-MailboxImportRequest -Mailbox <MailboxIdentity> | Format-List Name,FilePath,Mailbox,Status
