| Upcoming Changes to Entra Identity Protection Alert Settings in Defender XDRCategory:Microsoft Defender XDRNummer:MC1190195Status:stayInformed | [Introduction]
To improve alert clarity and reduce fatigue, Microsoft Defender XDR is introducing enhanced configuration options for identity-related alerts from Entra ID Protection. These updates are based on customer feedback requesting more granular control over risk-based alerting.
[When this will happen]
This change will begin rolling out as a public preview starting December 11, 2025.
[How this affects your organization]
- Who is affected:
- Admins using Microsoft Defender XDR with Entra ID Protection.
- What will happen:
- New alert configuration options will be available in the Defender XDR portal.
- Alert ingestion logic will now be explicitly tied to Entra ID Protection risk levels.
- Admins can choose which alerts to ingest into Defender XDR based on:
- High risk detections only
- High + Medium risk detections
- All detections
- Updated UI strings and visuals will improve clarity and usability.
- The default setting is changing from ingesting alerts of all severities to ingesting only alerts with severity = High. As a result, you may notice a reduction in alert volume, and some alert types will no longer be ingested into Defender XDR. You can always change the default setting to any of the other options – High + Medium or All detections, according to your organization’s needs.
[What you can do to prepare]
- No immediate action is required.
- If you wish to explore the new configuration options:
- Visit the Microsoft Defender XDR portal after December 11, 2025.
- Review and adjust alert settings based on your organization’s risk tolerance.
- Share this update with your security operations team.

| Flexible layout for Teams meetings with resizable dividerCategory:Microsoft TeamsNummer:MC1190199Status:stayInformed | [Introduction]
We’re introducing a new flexible layout option in future Teams meetings to give users more control over how shared content and participant videos appear. A resizable divider will let users adjust the space between shared content and the video gallery. Want to focus more on the presentation? Expand the content area. Prefer to see more people? Shrink the content area to make room for more video tiles. Users can also swap the position of content and participants to suit their viewing preference. This works with spotlighted speakers, pinned videos, and Speaker View, providing a more personalized meeting experience—especially helpful on larger or ultra-wide screens. Screenshot 1: When someone is sharing content or when you are in Speaker view, grab the divider between the left and right views to resize them. 
Screenshot 2. When you drag the divider to the left, you will see more people in the right gallery view. When you drag the divider to the right, you will see less people in the gallery but the content or speaker will become larger.
This message is associated with Microsoft 365 Roadmap ID 528930 and applies to Teams for Windows desktop and Teams for Mac desktop.
When this will happen:
- Targeted Release: Rolling out early January 2026, expected completion by late January 2026.
- General Availability (Worldwide and GCC): Rolling out early February 2026, expected completion by late March 2026.
How this will affect your organization:
Who is affected: All Teams users in Worldwide and GCC environments.
What will happen:
- Users will see a new resizable divider in Teams meetings during content sharing.
- Users can adjust layouts to prioritize content or participant video tiles.
- Users can swap positions of shared content and video gallery.
- Works with spotlighted speakers, pinned videos, and Speaker View.
- Enabled by default; no admin configuration required.
What you can do to prepare:
- No configuration is required; the feature is enabled by default.
- Update training materials and FAQs to explain:
- How to find and use the resizable divider.
- How to adjust layouts during content sharing and Speaker View.
- Communicate this change to helpdesk staff to prepare for user questions, especially from those with large or ultra-wide monitors.

| Archive File Classification Behavior Change for Windows EndpointsCategory:Microsoft PurviewNummer:MC1190206Status:stayInformed | [Introduction]
We are updating archive file classification behavior on Windows endpoints to align with cloud workloads. This change improves consistency, reduces noise in event reporting, and enhances performance when processing archive files.
[When this will happen:]
The change will begin rolling out late November 2025 and will apply automatically.
[How this affects your organization:]
- Who is affected: All organizations using Windows endpoints with archive file classification enabled.
- What will happen:
- Outer archive files (e.g., .zip, .rar) will now be classified directly.
- Classification will be atomic for improved consistency and reduced latency.
- Internal files within archives will no longer generate individual events; only the outer archive file will be reported.
- Context and label-based rules will not apply to files inside the archive.
- No admin or user action is required for this change to take effect.
[What you can do to prepare:]
- No action is required.
- If you maintain internal documentation on classification behavior, consider updating it to reflect these changes.
