Microsoft Teams: Private channels increased limits and transition to group compliance

Private channels now inherit team-level compliance policies instead of requiring separate user-level targeting, eliminating per-user mailbox copies of compliance messages. Private channel limits increase to support up to 1000 channels per team (previously 30) and 5000 members per channel (previously 250); meeting scheduling in private channels is now enabled.

Action required: Review and adjust compliance policies targeting private channels, as team-level policies will now apply uniformly across all channel types; validate private channel member counts and scheduling configurations.

Microsoft's description

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.
