This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago. In other words, “bring your own Copilot” is now a real thing in Word, Excel, PowerPoint, Outlook, and OneNote on desktop and mobile, with enterprise protections intact. “Bring your AI to work” is an important topic, and banning AI altogether might not be the answer.

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
