Remove-ActivityAlert
This cmdlet is available only in Security & Compliance PowerShell. For more information, see Security & Compliance PowerShell.

Use the Remove-ActivityAlert cmdlet to remove activity alerts.
For information about the parameter sets in the Syntax section below, see Exchange cmdlet syntax.

Parameters
-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.
