New-MailboxAuditLogSearch

 

Applies to: Exchange Online, Exchange Server 2016

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-MailboxAuditLogSearch cmdlet to search mailbox audit logs and have search results sent via email to specified recipients.

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

New-MailboxAuditLogSearch -EndDate <ExDateTime> -StartDate <ExDateTime> -StatusMailRecipients <MultiValuedProperty> [-Confirm [<SwitchParameter>]] [-DomainController <Fqdn>] [-ExternalAccess <$true | $false>] [-HasAttachments <$true | $false>] [-LogonTypes <MultiValuedProperty>] [-Mailboxes <MultiValuedProperty>] [-Name <String>] [-Operations <MultiValuedProperty>] [-ShowDetails <SwitchParameter>] [-WhatIf [<SwitchParameter>]]

This example creates a mailbox audit log search to search Ken Kwok and April Stewart's mailboxes for administrator and delegate logons from 1/1/2015 to 12/31/2015. Search results are sent to auditors@contoso.com by email.

New-MailboxAuditLogSearch "Admin and Delegate Access" -Mailboxes "Ken Kwok","April Stewart" -LogonTypes Admin,Delegate -StartDate 1/1/2015 -EndDate 12/31/2015 -StatusMailRecipients auditors@contoso.com

This example returns entries from the mailbox audit logs of all users in organization for any mailbox access by Microsoft datacenter administrators between September 1, 2015 and October 24, 2015. The search results are sent to admin@contoso.com.

New-MailboxAuditLogSearch -ExternalAccess $true -StartDate 09/01/2015 -EndDate 10/24/2015 -StatusMailRecipients admin@contoso.com

The New-MailboxAuditLogSearch cmdlet performs an asynchronous search of mailbox audit logs for the specified mailboxes and sends the search results by email to the specified recipients. The body of the email message contains search metadata such as search parameters and the time when the search request was submitted. The results are attached in an .xml file.

To search mailbox audit logs for a single mailbox and have the results displayed in the Exchange Management Shell window, use the Search-MailboxAuditLog cmdlet instead. To learn more about mailbox audit logging, see Mailbox audit logging in Exchange 2016.

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 audit logging" entry in the Messaging policy and compliance permissions topic.

 

Parameter Required Type Description

EndDate

Required

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".

StartDate

Required

Microsoft.Exchange.ExchangeSystem.ExDateTime

The StartDate parameter specifies the start 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".

StatusMailRecipients

Required

Microsoft.Exchange.Data.MultiValuedProperty

The StatusMailRecipients parameter specifies the email address of one or more recipients to whom search results are sent by email.

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.

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.

ExternalAccess

Optional

System.Boolean

The ExternalAccess parameter returns only audit log entries for mailbox access by a user outside of your organization. In Exchange Online, use this parameter to return audit log entries for access to a mailbox by Microsoft datacenter administrators.

HasAttachments

Optional

System.Boolean

The HasAttachments parameter filters the search by messages that have attachments. Valid values are:

  • $true   Only messages with attachments are included in the search.

  • $false   Messages with and without attachments are included in the search.

LogonTypes

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The LogonTypes parameter specifies the type of logons. Valid values include:

  • Admin   Audit log entries for mailbox access by administrator logons are returned.

  • Delegate   Audit log entries for mailbox access by delegates are returned, including access by users with Full Mailbox Access permission.

  • External   For Exchange Online mailboxes, audit log entries for mailbox access by Microsoft datacenter administrators are returned.

  • Owner   Audit log entries for mailbox access by the primary mailbox owner are returned. This value is available only in Exchange 2016 and also requires the ShowDetails switch.

Mailboxes

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The Mailboxes parameter specifies one or more mailboxes for which to retrieve mailbox audit log entries. If you don't specify a value, mailbox audit logs for all mailboxes in the Exchange organization are returned.

Name

Optional

System.String

The Name parameter specifies a name for the search.

Operations

Optional

Microsoft.Exchange.Data.MultiValuedProperty

The Operations parameter filters the search results by the operations that are logged by mailbox audit logging. Valid values for this parameter are:

  • Copy

  • Create

  • FolderBind

  • HardDelete

  • MailboxLogin This value is available only in Exchange 2016, and only when the LogonTypes parameter value Owner is also specified.

  • MessageBind

  • Move

  • MoveToDeletedItems

  • SendAs

  • SendOnBehalf

  • SoftDelete

  • Update

You can enter multiple values separated by commas.

ShowDetails

Optional

System.Management.Automation.SwitchParameter

The ShowDetails switch specifies that details of each log entry be retrieved. You don't need to specify a value with this switch.

WhatIf

Optional

System.Management.Automation.SwitchParameter

The WhatIf switch simulates the actions of the command. You can use this switch to view the changes that would occur without actually applying those changes. You don't need to specify a value with this switch.
