Details:

We are updating private channels to align with compliance model for all channels. After this change, compliance policies applied to the team (M365 Group) will apply to all channels in the team - across standard, private, and shared. Private channels will no longer need user level targeting of policies different from other channels, and private channel compliance messages will no longer be copied to user mailboxes, relying on a dedicated, internal mailbox per channel like shared channels. In addition, limits for private channels will be increased so each team can have more than 30 private channels, up to the 1000 total channel limit per team. Private channel member limits will increase from 250 to 5000. You will also be able to schedule meetings in private channels.

Microsoft Teams is making some updates to how private channels work, particularly in terms of compliance and limits. Imagine a team as a large office building. Each channel within the team is like a different room in that building. Previously, private channels were like special rooms with their own unique set of rules and security guards. Now, Microsoft is simplifying things by making all rooms follow the same building-wide rules, so the same compliance policies apply to every room, whether it's a standard, private, or shared channel.

This change means that private channels will no longer need their own individual security settings. Instead, they will rely on the same set of rules that apply to the entire team. Think of it like a security system that covers the whole building rather than having separate systems for each room. This will make it easier to manage and ensure that all rooms are secure in the same way.

Additionally, the limits on private channels are being increased. Previously, a team could only have up to 30 private channels, but now this limit is being raised significantly, allowing for more flexibility and growth. It's like expanding the office building to add more rooms without needing to worry about running out of space. The number of people who can be in a private channel is also increasing from 250 to 5000, making it possible to have larger groups working together in a private setting.

Moreover, you will now be able to schedule meetings directly in private channels, which is similar to being able to book a conference room for a meeting in that specific room, rather than having to find another space elsewhere.

These changes are designed to streamline the management of channels within Microsoft Teams, making it easier for everyone to work together efficiently while ensuring that compliance and security are maintained across the board.
