Description
You need to be assigned permissions before you can run this cmdlet. Although this article lists all parameters for the cmdlet, you might not have access to some parameters if they aren't included in the permissions assigned to you. To find the permissions required to run any cmdlet or parameter in your organization, see Find the permissions required to run any Exchange cmdlet.
Examples
Example 1
Set-M365DataAtRestEncryptionPolicy -Identity "Tenant Default Policy" -Enabled $false
This example disabled the Microsoft 365 data-at-rest encryption policy named Tenant Default Policy.
Example 2
Set-M365DataAtRestEncryptionPolicy -Identity "Tenant Default Policy" -Refresh
This example updates the Microsoft 365 data-at-rest encryption policy named Tenant Default Policy after one of the associated keys is rotated in the Azure Key Vault.
Parameters
-Confirm
Applicable: Exchange Online, Exchange Online Protection
The Confirm switch specifies whether to show or hide the confirmation prompt. How this switch affects the cmdlet depends on if the cmdlet requires confirmation before proceeding.
- Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause that forces you to acknowledge the command before proceeding. For these cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$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.
