This cmdlet enables admins to remove obsolete DomainKeys Identified Mail (DKIM) signing configurations directly from Exchange Online PowerShell, helping clean up configurations when   domains are removed from a tenant.<\/p>\n<p><b>[When this will happen]<\/b>  <\/p>\n<p>This feature is already enabled worldwide, including in special clouds.<br \/>  Rollout dates:  <\/p>\n<ul>

affected:<\/i><br \/>  Tenant administrators managing DKIM configurations in <i>Exchange Online<\/i> with either the Transport Hygiene management role or the Security Administrator role in Entra ID.  <\/p>\n<p><i>What will happen:<\/i>  <\/p>\n<ul>  <\/p>\n<li>Admins can now run <b>Remove-DkimSigningConfig<\/b> directly using Exchange Online PowerShell (requires ExO v3.7 module).<\/li>\n<p>  <\/p>\n<li>No escalation to Microsoft support is needed for DKIM cleanup.<\/li>\n<p>  <\/p>\n<li>Obsolete DKIM configurations for removed domains can be self-managed.<\/li>\n<p>  <\/p>\n<li>The cmdlet is available by default for eligible roles.<\/li>\n<li>This cmdlet does not replace any existing tools or processes; it introduces a new capability for tenant admins to manage DKIM cleanup independently.<\/li>\n<p>  <\/ul>\n<p>  <\/p>\n<p><b>[What you can do to prepare]<\/b>  <\/p>\n<ul>  <\/p>\n<li>Ensure you have the required role (Transport Hygiene or Security
