Smarter AI Workflows in Microsoft 365 Copilot has been announced on the roadmap: Tools, Source Control, and Agents

Tool Selection in Copilot Chat: Making AI Features More Discoverable One of the most helpful updates in my opinion, is the introduction of the new “Tools” button in Copilot Chat. Users will soon see this button directly in the chat prompt box, offering quick access to a curated set of Copilot features such as Researcher, Analyst, Pages, and image generation.  This will hopefully help users with an easier path to the different tools at their disposal. The feature is turned on by default, with no admin configuration required. This feature is associated with Roadmap ID 497298 , and is expected to roll out in the last weeks of August. Source Control in Copilot Chat: Scoped Responses for Greater Relevance Another user-friendly enhancement coming up, is the ability to scope Copilot Chat responses to specific content sources. This feature will allow users to define exactly which documents, folders, or repositories Copilot should reference when generating responses. It’s a subtle but power...

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.
