Copilot in Outlook: Prioritize my inbox

Microsoft is releasing a new feature for Copilot in Outlook: "Prioritize my inbox by Copilot". The feature can go through your inbox and analyse the content for you. it will then mark them as high and low priority and help you focus on the tasks that are important to you. When the feature rolls out, it will be implemented as an opt-in feature for users, and it will be a "limited seating" until there is enough capacity for all within the organization. When available and enabled, there will be ways to tell Copilot what is important to you. You can read more about this on the support pages for the feature. A couple of notes: It will only prioritize in your main inbox (Not subfolders) It will not work on shared mailboxes or groups This feature is associated with Microsoft 365 Roadmap ID 411302  and will start rolling out in April 2025

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.
