Examples

Example 1

Set-M365DataAtRestEncryptionPolicy -Identity "Tenant Default Policy" -Enabled $false

This example disabled the Microsoft 365 data-at-rest encryption policy named Tenant Default Policy.

Example 2

Set-M365DataAtRestEncryptionPolicy -Identity "Tenant Default Policy" -Refresh

This example updates the Microsoft 365 data-at-rest encryption policy named Tenant Default Policy after one of the associated keys has been rotated in the Azure Key Vault.

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.
