Microsoft 365 Copilot: New Navigation, Voice, and Context Enhancements Arriving Soon

on
Here are three new updates to the user interface of Microsoft Copilot. These releases improve usability, expand interaction options, and streamline how users incorporate work content into prompts. All three of these features were actually announced "a long time ago", and the initial release started almost 6 months ago. But I guess the setup is complicated, as the rollout hasn't completed yet. This only proves the importance of paying attention to the official roadmap and the tenant message center in order to understand when features are being implemented for your organization. Timelines may continue to evolve as deployments progress, and this summary includes the official reference IDs and documentation links for verification. Refreshed Navigation Experience There is a redesigned navigation experience for the Microsoft 365 Copilot app heading your way, delivering a cleaner, more efficient layout.

External Sharing in SharePoint and OneDrive is changing: What You Need to Know

on

In an ongoing effort to create a more secure environment by default, Microsoft is introducing an important security update that will affect how external users access content shared through SharePoint and OneDrive. Starting July 1, 2025, any links shared with external users before your organization enabled Microsoft Entra B2B integration will no longer work.

This change applies to all organizations that have already enabled or will enable SharePoint and OneDrive integration with Microsoft Entra B2B (Most organizations I have looked into so far). External users trying to use old links will see an error message saying the organization has updated its guest access settings. To regain access, the content must be reshared.

Highlights of how the change affects organizations who have enabled B2B:

  • All external sharing will require guest registration. External users must be added as guests in your Microsoft Entra directory.
  • Access will be managed through Microsoft Entra B2B Invitation Manager. This provides better tracking, lifecycle management, and control over guest access.
  • Multi-factor authentication (MFA) may be required. If your organization enforces MFA for guests, they will need to complete MFA before accessing shared content.
  • New sharing links will only work for registered guests. Anonymous access will no longer be supported in this model.

This means that external collaboration becomes more secure and auditable, but also requires a bit more setup and communication with your external partners. This change may have an impact on how you govern guest lifecycle management, from invitation to deactivation. Also verify your conditional access requirements for guests.

This update is a smart move by Microsoft to bring more control and visibility to external collaboration. While it may cause some short-term inconvenience, it’s a good opportunity to review and improve your sharing practices.
