Creating the required two CNAME required for Outbound DKIM signing using GoDaddy DNS management interface. In the next section, I will demonstrate how to create the two CNAME records, that will point to the Office 365 DKIM Selectors using the GoDaddy DNS management interface. Nov 01, 2019 Office 365. In this Microsoft official guide, you’ll discover how to create a DKIM record Office 365, how to configure DKIM for more than one domain, how to upgrade 1024-bit keys to 2048-bit DKIM encryption keys, and much more. To create a DKIM record on AWS, you have to accomplish five steps laid out in this documentation.
--> This cmdlet is available only in the cloud-based service.
Use the Rotate-DkimSigningConfig cmdlet to rotate the public and private DomainKeys Identified Mail (DKIM) signing policy keys for domains in a cloud-based organization. This cmdlet creates new DKIM keys and uses the alternate DKIM selector. Typically, you don't need to use this cmdlet, because Microsoft Office 365 automatically rotates your DKIM keys.

Syntax
Description
You need to be assigned permissions before you can run this cmdlet. Although this topic lists all parameters for the cmdlet, you may not have access to some parameters if they're not 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
This example rotates the DKIM signing policy for the contoso.com domain.
Parameters
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.
