New-MailboxSearch

 

Applies to: Exchange Online, Exchange Server 2016

Topic Last Modified: 2016-04-08

This cmdlet is available in on-premises Exchange Server 2016 and in the cloud-based service. Some parameters and settings may be exclusive to one environment or the other.

Use the New-MailboxSearch cmdlet to create a mailbox search and either get an estimate of search results, place search results on In-Place Hold or copy them to a Discovery mailbox. You can also place all contents in a mailbox on hold by not specifying a search query, which accomplishes similar results as Litigation Hold.

CautionCaution:
By default, mailbox searches are performed across all Exchange 2016 and Exchange 2013 Mailbox servers in an Exchange organization, unless you constrain the search to fewer mailboxes by using the SourceMailboxes parameter. To search mailboxes on Exchange 2010 Mailbox servers, run the command on an Exchange 2010 server.

For more information, see In-Place eDiscovery in Exchange 2016 and In-Place Hold and Litigation Hold in Exchange 2016.

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

New-MailboxSearch -Name <String> [-AllPublicFolderSources <$true | $false>] [-AllSourceMailboxes <$true | $false>] [-Confirm [<SwitchParameter>]] [-Description <String>] [-DomainController <Fqdn>] [-EndDate <ExDateTime>] [-EstimateOnly <SwitchParameter>] [-ExcludeDuplicateMessages <$true | $false>] [-Force <SwitchParameter>] [-IncludeKeywordStatistics <SwitchParameter>] [-IncludeUnsearchableItems <SwitchParameter>] [-InPlaceHoldEnabled <$true | $false>] [-InPlaceHoldIdentity <String>] [-ItemHoldPeriod <Unlimited>] [-Language <CultureInfo>] [-LogLevel <Suppress | Basic | Full>] [-MessageTypes <KindKeyword[]>] [-PublicFolderSources <PublicFolderIdParameter[]>] [-Recipients <String[]>] [-SearchQuery <String>] [-Senders <String[]>] [-SourceMailboxes <RecipientIdParameter[]>] [-StartDate <ExDateTime>] [-StatusMailRecipients <RecipientIdParameter[]>] [-TargetMailbox <MailboxIdParameter>] [-WhatIf [<SwitchParameter>]]

This example creates the mailbox search Legal-ProjectX. The search uses several parameters to restrict the search query:

  • SourceMailboxes   This parameter restricts the search to members of the DG-Marketing and DG-Executives distribution groups.

  • Recipients   This parameter specifies that the search includes all mail sent to the domain contoso.com.

  • SearchQuery   This parameter specifies a KQL query for messages with either the words project or report and for messages with attachments.

  • StartDate and EndDate   These parameters specify the start date of January 1, 2015, and end date of December 31, 2015, for the search.

  • TargetMailbox   This parameter specifies that search results should be copied to the discovery mailbox LegalDiscovery.

  • StatusMailRecipeints   This parameter specifies that the distribution group DG-DiscoveryTeam is to receive a notification when the search is complete.

New-MailboxSearch -Name "Legal-ProjectX" -SourceMailboxes DG-Marketing,DG-Executives -TargetMailbox LegalDiscovery@contoso.com -StartDate "01/01/2015" -EndDate "12/31/2015" -Recipients "@contoso.com" -SearchQuery "project report hasattachments:true" -StatusMailRecipients "DG-DiscoveryTeam"

This example creates an In-Place Hold Hold-ProjectX and places all members of the distribution group DG-Finance on hold. Because the search doesn't specify the SearchQuery and ItemHoldPeriod parameters, all messages in mailboxes returned are placed on indefinite In-Place Hold.

New-MailboxSearch -Name "Hold-ProjectX" -SourceMailboxes DG-Finance -InPlaceHoldEnabled $true

This example creates an In-Place Hold Hold-tailspintoys and places all members of the distribution group DG-Research on hold. Because the search specifies the SearchQuery parameter, only messages that match the search query are placed on indefinite In-Place Hold.

New-MailboxSearch -Name "Hold-tailspintoys" -SourceMailboxes DG-Research -SearchQuery "'Patent' AND 'Project tailspintoys'" -InPlaceHoldEnabled $true

In on-premises Exchange, this example creates an In-Place Hold named Hold for all PFs that places all content in all public folders on In-Place hold, with an unlimited hold duration.

New-MailboxSearch -Name "Hold for all PFs" -AllPublicFolderSources $true -InPlaceHoldEnabled $true

The New-MailboxSearch cmdlet creates an In-Place eDiscovery search or an In-Place Hold. Unless specified, mailboxes on all Mailbox servers in an organization are searched. You can stop, start, modify, or remove the search.

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 "In-Place eDiscovery" and "In-Place Hold" entries in the Messaging policy and compliance permissions in Exchange 2016 topic.

 

Parameter Required Type Description

Name

Required

System.String

The Name parameter specifies a friendly name for the search. If the value contains spaces, enclose the value in quotation marks (").

The value of this parameter is used to create the top-level folder that holds the search results in the target mailbox that's specified by the TargetMailbox parameter.

AllPublicFolderSources

Optional

System.Boolean

This parameter is available only in on-premises Exchange 2016.

The AllPublicFolderSources parameter specifies whether to include all public folders in the organization in the search. Valid values are:

  • $true   All public folders are included in the search. This value is required when:

    •  The value of the AllSourceMailboxes parameter is $false.

    And

    •  You don't specify one or more source mailboxes by using the SourceMailboxes parameter (the parameter value is blank [$null]).

  • $false   No public folders are included in the search. This is the default value. You can use this value when:

    •  The value of the AllSourceMailboxes parameter is $true.

    Or

    •  You specify one or more source mailboxes by using the SourceMailboxes parameter (the parameter value isn't blank [$null]).

AllSourceMailboxes

Optional

System.Boolean

This parameter is available only in on-premises Exchange 2016.

The AllSourceMailboxes parameter specifies whether to include all mailboxes in the search. Valid values are:

  • $true   All mailboxes are included in the search. This value is required when:

    •  The value of the AllPublicFolderSources parameter is $false.

    And

    •  You don't specify one or more source mailboxes by using the SourceMailboxes parameter (the parameter value is blank [$null]).

  • $false   All mailboxes aren't included in the search. This is the default value. You can use this value when:

    •  The value of the AllPublicFolderSources parameter is $true.

    Or

    •  You specify one or more source mailboxes by using the SourceMailboxes parameter (the parameter value isn't blank [$null]).

Confirm

Optional

System.Management.Automation.SwitchParameter

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.

Description

Optional

System.String

The Description parameter specifies a description for the search. The description isn't displayed to users. If the value contains spaces, enclose the value in quotation marks (").

DomainController

Optional

Microsoft.Exchange.Data.Fqdn

This parameter is available only in on-premises Exchange 2016.

The DomainController parameter specifies the domain controller that's used by this cmdlet to read data from or write data to Active Directory. You identify the domain controller by its fully qualified domain name (FQDN). For example, dc01.contoso.com.

EndDate

Optional

Microsoft.Exchange.ExchangeSystem.ExDateTime

The EndDate parameter specifies the end date of the date range.

Use the short date format that's defined in the Regional Options settings on the computer where you're running the command. For example, if the computer is configured to use the short date format mm/dd/yyyy, enter 09/01/2015 to specify September 1, 2015. You can enter the date only, or you can enter the date and time of day. If you enter the date and time of day, enclose the value in quotation marks ("), for example, "09/01/2015 5:00 PM".

EstimateOnly

Optional

System.Management.Automation.SwitchParameter

The EstimateOnly switch specifies that only an estimate of the number of items that will be returned is provided. You don't need to specify a value with this switch.

If you don't use this switch, messages are copied to the target mailbox.

ExcludeDuplicateMessages

Optional

System.Boolean

The ExcludeDuplicateMessages parameter eliminates duplication of messages in search results. Valid values are:

  • $true   Copy a single instance of a message if the same message exists in multiple folders or mailboxes. This is the default value.

  • $false   Copy all instances of a message if the same message exists in multiple folders or mailboxes.

Force

Optional

System.Management.Automation.SwitchParameter

The Force switch specifies whether to suppress warning or confirmation messages. You can use this switch to run tasks programmatically where prompting for administrative input is inappropriate. You don't need to specify a value with this switch.

IncludeKeywordStatistics

Optional

System.Management.Automation.SwitchParameter

The IncludeKeywordStatistics switch returns keyword statistics (number of instances for each keyword) in search results. You don't need to specify a value with this switch.

IncludeUnsearchableItems

Optional

System.Management.Automation.SwitchParameter

The IncludeUnsearchableItems switch specifies that items that couldn't be indexed by Exchange Search should be included in the results. You don't need to specify a value with this switch.

CautionCaution:
Unsearchable items aren't placed on hold for a query-based In-Place Hold. If you need to place unsearchable items on hold, you need to create an indefinite hold (a hold without specifying any search parameters, which provides functionality similar to Litigation Hold.

InPlaceHoldEnabled

Optional

System.Boolean

The InPlaceHoldEnabled parameter specifies whether to set an In-Place Hold on items in the search results. Valid values are:

  • $true   In-Place Hold is enabled on the search results.

  • $false   In-Place Hold isn't enabled on the search results. This is the default value.

You can't set an In-Place Hold on the search results when the AllSourceMailboxes parameter is $true.

importantImportant:
If you attempt to place a hold but don’t specify mailboxes using the SourceMailboxes parameter, the command may succeed but the mailboxes are not placed on In-Place Hold.

InPlaceHoldIdentity

Optional

System.String

This parameter is reserved for internal Microsoft use.

ItemHoldPeriod

Optional

Microsoft.Exchange.Data.Unlimited

The ItemHoldPeriod parameter specifies the number of days for the In-Place Hold onthe mailbox items (all mailbox items or the items that are returned in the search query results). The duration is calculated from the time the item is received or created in the mailbox. Valid values are:

  • An integer.

  • The value unlimited. This is the default value. Items are held until you remove the In-Place Hold by one of the following actions:

    •  You remove the search by using the Remove-MailboxSearch cmdlet.

    •  You remove the source mailbox from the search by using the Set-MailboxSearch cmdlet and the SourceMailboxes parameter.

    •  In on-premises Exchange, you remove all public folders from the search by using the Set-MailboxSearch cmdlet to change the AllPublicFolderSources parameter from $true to $false.

Language
