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.

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.
