New Year, New Momentum: Here are three Copilot updates to get you started into 2026

It's a new year, so I thought I'd start the year by mentioning three features already released, or soon going to be released. One of the features improves the workflow of sharing files with comments, the other improves the application specific Copilot, and the last feature makes it easer to find the nest available timeslot for a 1:1 meeting. As with all of my other posts, timelines can shift, and the timelines in this post is as written in the Message Center at the time of posting. AI-Summary experience when sharing files. With this new feature, copilot intent to help users share files with clearer context in just a few steps.

Prepare for: Multiple account access to Copilot in Microsoft 365

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.
