New-AdminAuditLogSearch -Name "Mailbox Quota Change Audit" -Cmdlets Set-Mailbox -Parameters UseDatabaseQuotaDefaults, ProhibitSendReceiveQuota, ProhibitSendQuota -StartDate 01/24/2015 -EndDate 02/12/2015 -StatusMailRecipients david@contoso.com, chris@contoso.com

This example finds all the administrator audit log entries that match the following criteria and sends the results to the david@contoso.com and chris@contoso.com SMTP addresses:

  • Cmdlets:Set-Mailbox

  • Parameters:UseDatabaseQuotaDefaults, ProhibitSendReceiveQuota, ProhibitSendQuota

  • StartDate: 01/24/2015

  • EndDate: 02/12/2015

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

New-AdminAuditLogSearch -ExternalAccess $true -StartDate 07/25/2015 -EndDate 10/24/2015 -StatusMailRecipients admin@contoso.com,pilarp@contoso.com -Name "Datacenter admin audit log"

This example returns entries in the administrator audit log of an Exchange Online organization for cmdlets run by Microsoft datacenter administrators between September 25, 2015 and October 24, 2015. The search results are sent to the admin@contoso.com and pilarp@contoso.com SMTP addresses and the text "Datacenter admin audit log" is added to the subject line of the message.

Required Parameters

-EndDate

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

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".

Type:ExDateTime
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-StatusMailRecipients

The StatusMailRecipients parameter specifies the recipients that should receive the administrator audit log report. The recipient must be a valid SMTP address.

If you want to specify more than one recipient, separate each SMTP address with a comma.

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

Optional Parameters

-Cmdlets

The Cmdlets parameter specifies the cmdlets you want to search for in the administrator audit log. Only the log entries that contain the cmdlets you specify are returned.

If you want to specify more than one cmdlet, separate each cmdlet with a comma.

Type:MultiValuedProperty
Position:Named
Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
-Confirm

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.

Type:SwitchParameter

Default value:None
Accept pipeline input:False
Accept wildcard characters:False
Applies to:Exchange Server 2010, Exchange Server 2013, Exchange Server 2016
