Microsoft Teams: Teams, Channels & Policies

What is Microsoft Teams?

Teams objects for the exam

Teams and channels

Teams and channel types

Feature	What It Is	Who Can Create	Example
Team	A collaboration space for a group of people	Anyone (or restricted by admin policy)	Marketing Team, Project Phoenix, IT Support
Standard channel	Open conversation topic within a team	Any team member	#general, #campaign-planning, #questions
Private channel	Restricted conversation — only invited members	Team members (if policy allows)	#leadership-only, #salary-discussions
Shared channel	Cross-team collaboration — members from different teams	Team owners (if policy allows)	#cross-team-budget shared between Finance and Marketing

Key exam concept: Every team has a General channel that can’t be deleted. Private channels have their own separate SharePoint site (with separate permissions). This matters for Copilot — private channel content is only visible to channel members.

Policies — admin controls

Policies are how admins control what users can do in Teams. The exam tests these:

Policy Type	What It Controls	Example
Meeting policies	Who can record, who can present, lobby settings	”Only organisers can record meetings”
Messaging policies	Emoji, GIFs, URL previews, message editing/deletion	”Disable GIFs in formal channels”
App permission policies	Which third-party apps are allowed	”Block all apps except Microsoft-approved ones”
Calling policies	Voice calling features, call forwarding	”Enable voicemail for all users”
Teams policies	Team feature settings, discovery, channel creation	”Only owners can create private channels”

💡 Scenario: Clearfield Council's Teams governance

Clearfield Council has strict communication rules. Director Chen configures:

1. Meeting policy: All meetings auto-recorded and stored for compliance
2. Messaging policy: URL previews enabled, GIFs disabled in council chambers channel
3. App policy: Only Microsoft first-party apps allowed — all third-party apps blocked
4. M365 Group creation policy (via Entra): Only IT and department heads can create new teams (prevents sprawl)
5. Guest access: Enabled ONLY for approved partner organisations (B2B guests added to teams)
6. External access: Federated chat/calls allowed ONLY with trusted domains

These policies apply per-user or per-group — Director Chen assigns stricter policies to councillors and standard policies to admin staff.

The Teams admin center

Key areas in admin.teams.microsoft.com:

Section	What You Manage
Teams → Manage teams	View, edit, archive, or delete teams
Users	Per-user policy assignments
Meetings → Meeting policies	Recording, transcription, lobby, screen sharing
Messaging → Messaging policies	Chat features, formatting, emoji
Teams apps → Permission/Setup policies	Which apps are available to users
Voice	Calling policies, auto-attendants, call queues
Org-wide settings	External access, guest access, Teams settings

Teams ↔ SharePoint connection

Every Teams team has a SharePoint team site behind it:

• The Files tab in a Teams channel = a SharePoint document library
• Files shared in Teams chat are stored in the sender’s OneDrive
• Private channels get their own separate SharePoint site

This means SharePoint permissions and Teams membership are tightly linked. When Copilot searches Teams content, it’s actually querying SharePoint and Microsoft Graph.

Question

What's the connection between Teams and SharePoint?

Click or press Enter to reveal answer

Answer

Every Teams team has a SharePoint team site. The Files tab is a SharePoint document library. Private channels get their own separate SharePoint site. This means SharePoint permissions affect what Copilot can see in Teams content.
