Microsoft 365 No DKIM keys saved for this domain: fix with Windows PowerShell

Sometimes a newly added domain in Microsoft EOP will not let you enable DKIM from the web user interface. If you are facing issues when attempting to enable DKIM for a domain in Microsoft 365 Exchange Admin Portal by not having the option to enable DKIM, but the “No DKIM keys saved for this domain” message, as seen in the screenshot below, you are able to fix this with Windows PowerShell. So what can we do in this case? 

Follow the steps:
