Prepare for: Multiple account access to Copilot in Microsoft 365

on
There is a new (As of January 30, 2025) policy setting is available in Cloud Policy, which will enable multiple account access to Copilot in Microsoft 365 desktop and mobile apps, allowing users to utilize Copilot across different signed-in accounts.  The feature itself will allow a user to use a fully licensed Copilot feature from one tenant on "any" document available to them in a tenant they have access to. No matter if the user has Copilot in any of the other tenants. The feature will be rolled out globally from early March 2025 and is expected to be completed by late March 2025, but organizations might want to look into this policy and understand how it may or may not impact their existing security policies. I recommend reading up on the following article , where details about what the user can access in different scenarios are described. Here are some of the things to take into consideration:  Copilot's data protection is based on the identity used to access the fil...

Microsoft Copilot coming to Teams and Outlook for users with Entra accounts

on

Microsoft is expanding the Microsoft Copilot for users with Entra licenses, and the distinctions between the different versions are becoming increasingly blurred. Initially, when Copilot was released, there was the "Bing/Chat" version for commercial use. This version did not necessarily protect company data from being harvested or used for training purposes. Microsoft also released the enterprise-protected Copilot version for all users with an M365 E5 license about the same time. Although this version did not integrate searches or features with company data, it at least promised to keep data and queries private to the organization when used.

Subsequently, Microsoft revised the requirements for accessing the enterprise-protected version of Copilot, making it available to everyone with an Entra User License, effectively including virtually anyone within an M365 tenant.

Now, further changes are on the horizon for this group of users. Starting mid-January, Microsoft will enhance this offering even further. Soon, users will be able to access Copilot directly from Teams and Outlook, in addition to the existing web interface (BizChat). This is mentioned in Roadmap ID 420330

While I believe this is a positive development, it may cause confusion among users who might assume they now have Copilot licenses. Therefore, it is important to train and inform your users about the differences in behavior of these apps and integrations for users with and without a Copilot license. For instance, explaining why they might experience different results based on the actual license and version of Copilot they are using is essential.

If you want to help your users find the app, an admin can follow this guide to pin the app for the endusers. Or you can let them find it and pin it for themselves.
