A new Exchange Online admin policy will let admins set a tenant-wide default for using commas as recipient separators in Outlook mail compose and reply. Rollout starts April 2026. Users can override unless locked by policy. No automatic changes; no action required.

Today, sharing a folder requires manually sharing each parent folder in the hierarchy. Outlook will simplify this by allowing users to share a folder in a single step, automatically applying the required permissions to its parent folders. Before sharing, users will clearly see which folders (including parent folders) will be shared. This removes manual effort while keeping users informed and in control.
We are expanding Microsoft Purview DLP for Microsoft 365 Copilot and Copilot Chat to safeguard web searches containing sensitive data. This real-time control helps organizations mitigate data leakage and oversharing risks by preventing Microsoft 365 Copilot and agents from using sensitive data for external web search. This capability currently extends to Microsoft 365 Copilot and agents built in Copilot Studio that are published to Microsoft 365 Copilot.
We’ve released updates to the following update channel for Microsoft 365 Apps:
Admins can now set separate retention policies for Copilot and AI app interactions in Microsoft Purview, allowing faster deletion if needed. This feature, rolling out from mid-March to May 2026, enhances data lifecycle management and compliance controls for generative AI content.
Outlook for iOS and Android will add an option to search all filtered messages when more exist beyond locally synced items, improving clarity without changing sync behavior or admin settings. This rollout begins mid-March 2026 and requires no admin action. Users applying filters like Unread or Flagged are affected.
Starting late March to April 2026, Microsoft 365 Copilot app will allow admins to add a branded footer with their organization’s logo, confirming a trusted Copilot environment. This feature is off by default, requires admin setup via the Microsoft 365 admin center, and affects all tenants using the app.
Microsoft Fabric will introduce workspace-level IP firewall rules in Public Preview from mid-January to early March 2026, allowing workspace admins to restrict inbound access by IP allowlists. Tenant admins control this feature via a toggle in the Fabric admin portal, enhancing workspace data security.
