Description
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 Server.
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't 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.
Examples
Example 1
New-MailboxAuditLogSearch "Admin and Delegate Access" -Mailboxes "Ken Kwok","April Stewart" -LogonTypes Admin,Delegate -StartDate 1/1/2018 -EndDate 12/31/2018 -StatusMailRecipients auditors@contoso.com
This example creates a mailbox audit log search to search Ken Kwok and April Stewart's mailboxes for administrator and delegate logons from 1/1/2018 to 12/31/2018. Search results are sent to auditors@contoso.com by email.
Example 2
New-MailboxAuditLogSearch -ExternalAccess $true -StartDate 09/01/2018 -EndDate 10/24/2018 -StatusMailRecipients admin@contoso.com
This example returns entries from the mailbox audit logs of all users in organization for any mailbox access by Microsoft datacenter administrators between September 1, 2018 and October 24, 2018. The search results are sent to admin@contoso.com.
Parameters
-Confirm
Applicable: Exchange Server 2010, Exchange Server 2013, Exchange Server 2016, Exchange Server 2019, Exchange Server SE, Exchange Online
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$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.
