“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. 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. Whether sanctioned or shadow, AI has already entered everyday knowledge work.

Bing Enterprise Chat enabled by default for all

There are a lot of great things happening in the generative AI space these days. Microsoft is determined to be a part of this revolution, and they have announced a lot of coming services. One of the new features that was released a few weeks ago was the Bing Chat Enterprise (BCE) which is a new feature that enables your organization to use AI-powered chat for work while keeping your user and business data protected. 

BCE is available in preview to Microsoft 365 customers with E3, E5, A3, A5 (faculty only), Business Standard and Business Premium licenses, but not to customers in government clouds. 

At first BCE was an opt-in feature, but it is now turned on by default for eligible customers who have not previously opted out of it. Should your organization want to opt-out of BCE, it is possible to do so through the BCEAdmin panel 

BCE and Bing Chat might seem similar, but Bing Chat does not offer commercial data protection and should only be used for personal use. BCE will now be available on bing.com/chat, Edge sidebar, and Windows Copilot. You will not need to enable Microsoft Search in Bing to access BCE after mid-September.
