What's changed: Created MS-700 Chapter 3 (domain: Manage teams, channels, chats, and apps). Create/manage teams (Advisor for Teams; create via admin center/client/PowerShell/Graph/from existing groups or templates; template policies; owner/member; privacy/sensitivity; frontline teams), channels and chats (standard/private/shared channels, channel settings, messaging policies), and apps (org-wide app settings, app setup policies, app permission policies, consent/block, extensibility tabs/messaging extensions/workflows, Teams app store, upload).
3.2Channels and chats
Understand standard/private/shared channels, adding/editing/removing channels, channel settings, private/shared channel membership, and messaging policies.
Channels differ by who can access them. Chat features are controlled by messaging policies.
3.2.1Channel types
A standard channel is accessible to all team members. A private channel is accessible only to a limited subset of team members and has a dedicated SharePoint site. A shared channel (Teams Connect) can be shared with other teams or external orgs, and participants access the channel without joining the team. Choose by requirement (everyone/limited/external).
3.2.2Channel settings and messaging policies
Channels can be added/edited/removed, and channel settings configure moderation, mentions, connectors, etc. Messaging policies allow/disallow chat features per user (edit/delete messages, read receipts, giphy/stickers, priority, translation). Distinguish "channel type and access" from "chat feature control (messaging policy)."
Cues: "all team members can access" = standard channel. "limited subset only, dedicated SharePoint" = private channel. "shared with other teams/external orgs, no team join" = shared channel. "control chat features like edit/delete or giphy" = messaging policy.
Watch the mix-ups: (1) Standard (everyone) vs private (limited members) vs shared (external). (2) A private channel has its own SharePoint site. (3) Messaging policies (chat feature control) are separate from channel type. (4) External use of shared channels requires B2B direct connect + cross-tenant access (see ch2).
3.2.3Section summary
- Standard = all members; private = limited members (own SharePoint); shared = other teams/external
- Channel settings configure moderation; messaging policies allow/disallow chat features
- External shared channels require B2B direct connect + cross-tenant access
