This cmdlet is available in on-premises Exchange and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.
Use the New-MailboxRestoreRequest cmdlet to restore a soft-deleted or disconnected mailbox. This cmdlet starts the process of moving content from the soft-deleted mailbox, disabled mailbox, or any mailbox in a recovery database into a connected primary or archive mailbox.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax (https://technet.microsoft.com/library/bb123552.aspx).

Syntax

Description

When mailboxes are moved from one database to another, Exchange doesn't fully delete the mailbox from the source database immediately upon completion of the move. Instead, the mailbox in the source mailbox database is switched to a soft-deleted state, which allows mailbox data to be accessed during a mailbox restore operation by using the new MailboxRestoreRequest cmdlet set. The soft-deleted mailboxes are retained in the source database until either the deleted mailbox retention period expires or you use the Remove-StoreMailbox cmdlet to purge the mailbox.

To view soft-deleted mailboxes, run the Get-MailboxStatistics cmdlet against a database and look for results that have a DisconnectReason with a value of SoftDeleted. For more information, see Example 1 later in this topic.

A mailbox is marked as Disabled a short time after the Disable-Mailbox or Remove-Mailbox command completes.

The mailbox won't be marked as Disabled until the Microsoft Exchange Information Store service determines that Active Directory has been updated with the disabled mailbox's information. You can expedite the process by running the Update-StoreMailboxState cmdlet against that database.

Exchange retains disabled mailboxes in the mailbox database based on the deleted mailbox retention settings configured for that mailbox database. After the specified period of time, the mailbox is permanently deleted.

To view disabled mailboxes, run the Get-MailboxStatistics cmdlet against a database and look for results that have a DisconnectReason with a value of Disabled. For more information, see Example 1 later in this topic.

You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not 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 (https://technet.microsoft.com/library/mt432940.aspx).

Examples

-------------------------- Example 1 --------------------------

To create a restore request, you must provide the DisplayName, LegacyDN, or MailboxGUID for the soft-deleted or disabled mailbox.

This example uses the Get-MailboxStatistics cmdlet to return the DisplayName, LegacyDN, MailboxGUID, and DisconnectReason for all mailboxes on mailbox database MBD01 that have a disconnect reason of SoftDeleted or Disabled.

-------------------------- Example 2 --------------------------

This example restores the source mailbox with the MailboxGUID 1d20855f-fd54-4681-98e6-e249f7326ddd on mailbox database MBD01 to the target mailbox with the alias Ayla.

-------------------------- Example 3 --------------------------

This example restores the content of the source mailbox with the DisplayName of Tony Smith on mailbox database MBD01 to the archive mailbox for Tony@contoso.com.

Parameters

The AcceptLargeDataLoss switch specifies the request should continue even if a large number of items in the source mailbox can't be copied to the target mailbox. You need to use this switch if you set either the BadItemLimit or LargeItemLimit parameters to a value of 51 or higher. Otherwise, the command will fail.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

The AllowLegacyDNMismatch switch specifies that the operation should continue if the LegacyExchangeDN of the source physical mailbox and the target mailbox don't match. You don't need to specify a value with this switch.

By default, this cmdlet checks to make sure that the LegacyExchangeDN on the source physical mailbox is present on the target user in the form of the LegacyExchangeDN or an X500 proxy address that corresponds to the LegacyExchangeDN. This check prevents you from accidentally restoring a source mailbox into the incorrect target mailbox.

Type:SwitchParameter
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

The AssociatedMessagesCopyOption parameter specifies whether associated messages are copied when the request is processed. Associated messages are special messages that contain hidden data with information about rules, views, and forms. By default, associated messages are copied. This parameter accepts the following values:

  • DoNotCopy: The associated messages aren't copied. This is the default option.

  • MapByMessageClass: This option finds the corresponding associated message by looking up the MessageClass attribute of the source message. If there's an associated message of this class in both source and target folders, it overwrites the associated message in the target. If there isn't an associated message in the target, it creates a copy in the target.

  • Copy: This option copies associated messages from the source to the target. If the same message type exists both in the source and the target location, these associated messages are duplicated.

Content filtering doesn't apply to associated messages.

Type:DoNotCopy MapByMessageClass Copy
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

The BadItemLimit parameter specifies the maximum number of bad items that are allowed before the request fails. A bad item is a corrupt item in the source mailbox that can't be copied to the target mailbox. Also included in the bad item limit are missing items. Missing items are items in the source mailbox that can't be found in the target mailbox when the request is ready to complete.

Valid input for this parameter is an integer or the value unlimited. The default value is 0, which means the request will fail if any bad items are detected. If you are OK with leaving a few bad items behind, you can set this parameter to a reasonable value (we recommend 10 or lower) so the request can proceed. If too many bad items are detected, consider using the New-MailboxRepairRequest cmdlet to attempt to fix corrupted items in the source mailbox, and try the request again.

If you set this value to 51 or higher, you also need to use the AcceptLargeDataLoss switch. Otherwise, the command will fail.

Type:Unlimited
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

The BatchName parameter specifies a descriptive name for restoring a batch of mailboxes. You can use the name in the BatchName parameter as a string search when you use the Get-MailboxRestoreRequest cmdlet.

Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

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 being changed to Completed.

Type:Unlimited
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Online

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.

Archive Name And Parameters Magazine 2017

The Name parameter specifies the name of the specific request for tracking and display purposes. Because you can have multiple restore requests per mailbox, Exchange precedes the name with the mailbox's alias. For example, if you create an export request for a user's mailbox that has the alias Kweku and specify the value of this parameter as RestoreFailedMoves, the identity of this export request is KwekuRestoreFailedMoves.

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

Creates an archive, or zipped file, from specified files and folders.

Syntax

Description

The Compress-Archive cmdlet creates a zipped (or compressed) archive file from one or morespecified files or folders. An archive file allows multiple files to be packaged, and optionallycompressed, into a single zipped file for easier distribution and storage. An archive file can becompressed by using the compression algorithm specified by the CompressionLevel parameter.

The Compress-Archive cmdlet relies upon the Microsoft .NET API System.IO.Compression.ZipArchiveto compress files. Therefore, the maximum file size that is 2 GB. This is a limitation of theunderlying API.

Examples

Example 1: Create an archive file

This command creates a new archive file, Draft.zip, by compressing two files, Draftdoc.docx anddiagram2.vsd, specified by the Path parameter. The compression level specified for thisoperation is Optimal.

Example 2: Create an archive file (using LiteralPath)

This command creates a new archive file, Draft.zip, by compressing two files, Draft doc.docx andDiagram [2].vsd, specified by the LiteralPath parameter. The compression level specified for thisoperation is Optimal.

Example 3: Create an archive with wildcard characters

This command creates a new archive file, Draft.zip, in the C:Archives folder. The new archivefile contains every file in the C:Reference folder, because a wildcard character was used inplace of specific file names in the Path parameter.

Notice that the file name extension .zip was not added to the value of the DestinationPathparameter. PowerShell appends the .zip extension to the file name automatically. The specifiedcompression level is Fastest, which might result in a larger output file, but compresses a largenumber of files faster.

Example 4: Update an existing archive file

This command updates an existing archive file, Draft.Zip, in the C:Archives folder.

The command is run to update Draft.Zip with newer versions of existing files that came from theC:Reference folder, and also to add new files that have been added to C:Reference sinceDraft.Zip was initially created.

Example 5: Create an archive from an entire folder

This command creates an archive from an entire folder, C:Reference.

Notice that the file name extension .zip was not added to the value of the DestinationPathparameter. PowerShell appends the .zip extension to the file name automatically.

Parameters

Specifies how much compression to apply when you are creating the archive file. Faster compressionrequires less time to create the file, but can result in larger file sizes. The acceptable valuesfor this parameter are:

  • Fastest. Use the fastest compression method available to decrease processing time; this can resultin larger file sizes.
  • NoCompression. Do not compress the source files.
  • Optimal. Processing time is dependent on file size.

If this parameter is not specified, the command uses the default value, Optimal.
