Microsoft 365 updates on new Copilot capabilities

on
Microsoft has announced a set of upcoming enhancements that continue to expand the value of Copilot across Microsoft 365. These updates introduce new ways for users to manage collaboration and meeting experiences with less context switching and more control. As always, timelines may shift as development progresses. I have provided the official reference IDs and documentation links for your convenience. Schedule meetings directly from Copilot Chat The first update introduces a new capability that allows users to schedule meetings directly from Copilot chat. This feature reached general availability worldwide with rollout completed by late January 2026. It enables users to find available times, book rooms, draft agendas, and send invitations entirely within the chat experience, reducing the need to move between applications and helping streamline everyday workflow.

Prepare for: Multiple account access to Copilot in Microsoft 365

on

There is a new (As of January 30, 2025) policy setting is available in Cloud Policy, which will enable multiple account access to Copilot in Microsoft 365 desktop and mobile apps, allowing users to utilize Copilot across different signed-in accounts. 

The feature itself will allow a user to use a fully licensed Copilot feature from one tenant on "any" document available to them in a tenant they have access to. No matter if the user has Copilot in any of the other tenants. The feature will be rolled out globally from early March 2025 and is expected to be completed by late March 2025, but organizations might want to look into this policy and understand how it may or may not impact their existing security policies.

I recommend reading up on the following article, where details about what the user can access in different scenarios are described.

Here are some of the things to take into consideration: 

  • Copilot's data protection is based on the identity used to access the file, ensuring enterprise data protection regardless of the account used. 
  • The setting for web grounding in Copilot is also identity-based. If web grounding is disabled for a particular identity, it will remain disabled even when accessing Copilot from another account.
  • If a user is accessing a document in a different tenant, work grounded data from the home tenant will NOT be available
  • The feature will be available in most of the major apps. 
For organizations considering to restrict this behaviour, Microsoft has provided the following Learn Article.
