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

on
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. Microsoft’s new multi‑account access offers a safer path where employees can use Copilot from their personal Microsoft 365 subscriptions on work files, while the file’s access, auditing, and compliance still flow through the work identity and tenant.

Copilot Wave two "Memory and Personalization" requires: Enhanced Personalization

New admin control: Enhanced Personalization Control

With the announcement of Copilot wave two, some may have noticed one of the new features called "Memory and Personalization". For this feature to work, copilot must learn and store some of the user's personal information. How else will it understand the user, and actually improve on the responses given over time. Some are welcoming this new feature, as competitors have already rolled out similar functionality, but others might be a bit hesitant to have this information stored.

I am guessing that is why Microsoft has introduced a new data processing control for Microsoft 365 Copilot. This control, is now called Enhanced Personalization, and is already available for Global Admins to configure for their tenants. 

What is Enhanced Personalization?

Enhanced Personalization is a forward-looking control that will become part of the default configuration for Microsoft 365 Copilot licenses. This control allows Microsoft to process user communications data, such as Teams chats and Outlook emails, to provide a more personalized experience. The goal is to enhance the baseline personalization already offered by Microsoft 365 Copilot. (Read more about it here).

The feature will be on by default.

The new control will be defaulted to "on" for Microsoft 365 Copilot licenses. This means that Microsoft will process user communications data to enhance their experience. It's important to note that this consent is fully revocable, and no features currently use this control. However, it is already now possible to configure this feature through Microsoft Graph.
