“Bring your AI to work” is here: Microsoft edition - What Multiple Account Access to Copilot means

Multiple Account Access to Copilot On October 1. 2025 Microsoft released a blog post explaining how employees now can use Copilot from their personal 365 plans to work on organizational data. This is of course, an extension of the already existing "Multi account" feature that was released for corporate accounts a "couple of months" ago.

This update is currently planned to be complete by the end of April 2025 but keep an eye on Microsoft 365 Roadmap ID 422725 for changes.
