Reference

Module:: ExchangePowerShell

Applies to:: Security & Compliance

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

Note: Activity alerts have been effectively replaced by alert policies and the corresponding *-ProtectionAlert cmdlets. For more information about alert policies, see Alert policies in Microsoft 365.

Use the Remove-ActivityAlert cmdlet to remove activity alerts.

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

Syntax

Remove-ActivityAlert
      [-Identity] <PolicyIdParameter>
      [-Confirm]
      [-ForceDeletion]
      [-WhatIf]
      [<CommonParameters>]

Description

To use this cmdlet in Security & Compliance PowerShell, you need to be assigned permissions. For more information, see Permissions in the Microsoft Defender portal or Permissions in the Microsoft Purview compliance portal.

Examples

Example 1

Remove-ActivityAlert -Identity "All Mailbox Activities"

This example removes the activity alert named All Mailbox Activities.

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.
