Microsoft is unlocking the "Full Potential" of Private Channels in Microsoft Teams: What You Need to Know

on
It has been a while since I posted something just about a Microsoft Teams update, as a lot have been Copilot in Teams to be honest. But here is a real Microsoft Teams update I think is worth knowing about, and it involves Security and Compliance as well. Microsoft is rolling out a "major" update to private channels in Teams, starting in late September 2025 and continuing through mid-December. This biggest change in this update is a shift in how private channel data is stored from individual user mailboxes to a dedicated channel mailbox. Not only will this simplifie compliance management, it will also and align private channels with shared channels, making governance and experience more consistent across Teams. This update promises to increase the support up to 1000 channels per team and 5000 members per channel, removing previous limitations.

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

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.
