Thank you for your patience.  <\/p>\n<p>To enhance security and reduce potential data exposure, we are updating the behavior of the  <code>Get-FederationInformation<\/code> cmdlet in Exchange Online. This change limits the scope of domain data returned by the cmdlet.<\/p>\n<p>[When this will happen:]<\/p>\n<p>General Availability (Worldwide, GCC, GCC-High, DoD): Rollout will begin in late June 2025 (previously mid-June) and is expected to complete by late August 2025 (previously early July).<\/p>\n<p>  <\/p>\n<p>[How this affects your organization:]<\/p>\n<p>Previously, the <code>Get-FederationInformation<\/code> cmdlet returned all federated domain information in the DomainNames field. After this update, the cmdlet will only return domain information that is explicitly passed as a parameter. This change may   impact scripts or tools that rely on retrieving all federated domains by default.  <\/p>\n<p>There is no change to the cmdlet\u2019s availability or core functionality\u2015only the scope of data returned is affected.  <\/p>\n<p>[What you can do to prepare:]<\/p>\n<ul>\n<li>Review any automation, scripts, or tools that use the <code>Get-FederationInformation<\/code> cmdlet to ensure they explicitly pass the required domain(s) as parameters.  <\/li>\n<li>Communicate this change to your Exchange Online administrators and support teams to avoid confusion or unexpected results.  <\/li>\n<li>For more details, refer to the official blog post: <a
