Scope of impact
Users attempting to perform any of the outlined impact scenarios may be affected by this event.
Preliminary root cause
An issue within a core authentication configuration used by multiple Microsoft 365 services is resulting in impact.
Note: Microsoft SharePoint displays a new visual element: a rounded frame around the content of your pages (see image).
This is a purely cosmetic change from Microsoft and has no impact on your intranet's functionality.
If you'd prefer to remove this frame, our support team can do so for you with a small addition to the css styling. Just let us know.
Warning: Microsoft CSP Enforcement & Impact on Script Editors
Starting March 1, 2026, Microsoft will enforce stricter Content Security Policies (CSP) across all tenants. As a result, custom Script Editors and solutions that rely on inline scripts or external script sources may stop working. This can cause certain web parts or customizations to fail to load or behave unexpectedly.

We provide more info about this Microsoft update and possible solutions in our knowledge base:

If you experience any issues, please contact our support desk. They can help troubleshooting, updating your Involv intranet to the latest software version and adding external scripts as trusted sources.
Warning: Styling Impact From Recent Microsoft SharePoint Updates
Microsoft has rolled out platform-level changes to SharePoint that affect how custom CSS is rendered. As a result, some styling on your Involv intranet may display incorrectly. Common symptoms include article page titles or pagination numbers appearing in unexpected colors, and extra header bars becoming visible.
General layout issues (such as extra header bars) will be addressed through standard Involv updates and are covered under your software assurance. Custom styling issues require individual CSS adjustments specific to your intranet — this work is always billed separately. If you need an immediate styling patch before the next update, please note that this is also billed as additional work.
If you experience any issues, please contact our support desk. We'll assess which category your issue falls into and confirm the scope and estimate with you before any work begins.
