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. Teams will also allow meetings to be scheduled directly within private channels, enhancing collaboration.  For organizations using Micr...

Features in Teams are being rolled out at a really high speed these days, and I am a little behind on sharing my thoughts on them. So here is my summary of what I think are some of the important updates coming soon.

Microsoft Lists in Teams:
The release of Microsoft lists is going to be available on many platforms, and also Teams. The feature will be available by default for all users, channels and teams, unless policies are in place to restrict access. A user will have a mix of lists, both personal and related to different channels and teams. I recommend you share this link with your organization, to prepare for what will be coming in September and October: Get started with Microsoft Lists

New calling and meeting experience:
One of the biggest changes this summer, was the preview release of new calling and meeting experience. This will probably be a default setting (according to earlier posts), but if you want to experience some of the new great features you need to turn them on yourself.

Click on your avatar, and select "settings". Within the settings, you will have to check the box next to "Turn on new meeting experience (New meetings and calls will open in separate windows. Requires restarting Teams.)" and restart Teams.

After you've done this, multiple things will be available:

  • All new calls and meetings will pop out in a separate window, so you can easily access meeting notes or other relevant information in the regular Teams window without minimizing the call.
  • Large gallery view (up to 49 streams, available for selection once 10 participants have joined with video)
  • Together mode. A new mode where you get to see everyone as if they were seated in an auditorium.
  • Meeting controls are moved away from the middle of the video feed to a separate bar at the top.
Read more about these features and more at the TechCommunity These features should already be available in most tenants.

Speaker attribution in Live Captions:
Live caption is getting an improvement that will help identify who said what during a meeting. Rolling out by the end of August, this feature will list the speaker's name in front of the captions printed on screen.
