New-MailboxAuditLogSearch

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.

This parameter is available only in on-premises Exchange.

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.

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 09/01/2018 to specify September 1, 2018. 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, "09/01/2018 5:00 PM".

The ExternalAccess parameter specifies whether to return only audit log entries for mailbox access by users that are outside of your organization. In Exchange Online, this parameter returns audit log entries for mailbox access by Microsoft datacenter administrators. Valid values are:

$true: Audit log entries for mailbox access by external users or Microsoft datacenter administrators are returned.

$false: Audit log entries for mailbox access by external users or Microsoft datacenter administrators are ignored. This is the default value.

This parameter is available only in the cloud-based service.

The GroupMailbox switch is required to include Microsoft 365 Groups in the search. You don't need to specify a value with this switch.

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.

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

• 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 requires the ShowDetails switch.

You can enter multiple values separated by commas.

The Mailboxes parameter specifies the mailbox to retrieve mailbox audit log entries from.

You can enter multiple values separated by commas. If the values contain spaces or otherwise require quotation marks, use the following syntax: "Value1","Value2",..."ValueN".

If you don't specify a value, mailbox audit logs for all mailboxes in the organization are returned.

The Name parameter specifies a name for the search. The maximum length is 64 characters. If the value contains spaces, enclose the value in quotation marks (").

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

• Copy
• Create
• FolderBind
• HardDelete
• MailboxLogin
• MessageBind
• Move
• MoveToDeletedItems
• SendAs
• SendOnBehalf
• SoftDelete
• Update

You can enter multiple values separated by commas.

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

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 09/01/2018 to specify September 1, 2018. 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, "09/01/2018 5:00 PM".

The StatusMailRecipients parameter specifies the email address where the search results are sent. You can specify multiple values separated by commas.

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.
