“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.

Wonders of all wonders this solved my problems.
