Concepts (54)
Microsoft Teams
A collaboration hub for chat, meetings, calls, and teamwork; files are stored behind the scenes in SharePoint/OneDrive.
Prerequisites: OneDrive
Related: SharePoint
Teams admin center
The dedicated admin center for Microsoft Teams teams, channels, and policies. Policies control the scope of meetings, messaging, and apps.
Prerequisites: Microsoft Teams
Auto attendant
A Teams phone feature that greets inbound calls with an IVR (interactive voice response) menu and routes them to a department, person, or voicemail based on business hours and dialed input. It is assigned a resource account to hold a phone number and configured with after-hours messages and call-flow branching.
Prerequisites: Microsoft Teams、Teams Phone
Related: Call queue、Resource account
Call queue
A Teams phone feature that distributes inbound calls to a group of agents according to a routing method (serial, round-robin, longest idle, etc.), playing hold music or announcements until answered. Assigned a resource account to hold a phone number, it is commonly used as the first point of contact for call centers or help desks.
Prerequisites: Microsoft Teams、Teams Phone
Related: Auto attendant、Resource account
Meeting customization policies
A Teams Premium policy (Teams admin center: Meetings > Customization policies) controlling the visual branding of meetings. It defines meeting themes—an org logo, brand color, and custom image, up to five per policy—and custom meeting background images (up to 50 per policy) available to participants, applied per tenant or per user. Distinct in purpose from regular meeting policies (which control usable features like recording or chat), as this handles appearance only.
Prerequisites: Teams admin center、Microsoft Teams
Related: Meeting templates、Meeting policies
Microsoft Purview
Microsoft's unified governance and compliance solutions: information protection, data lifecycle, risk management, eDiscovery, and auditing, plus cross-estate data governance via the data map/catalog (integrating the former Azure Purview).
Related: Purview Information Protection
Teams Phone
A cloud telephony capability that lets Microsoft Teams place and receive PSTN calls. Phone numbers are provided via Calling Plans, Operator Connect, or Direct Routing.
Prerequisites: Microsoft Teams
Related: Number provisioning (Calling Plan / Operator Connect / Direct Routing)
Meeting templates
A feature that predefines default meeting options (who is a presenter, lobby handling, recording permission, etc.) as a blueprint for specific meeting scenarios (e.g., webinar-like internal events, interviews). Admins can lock settings within a template so organizers cannot override them. Templates are created and assigned per scenario in the Teams admin center.
Prerequisites: Teams admin center、Microsoft Teams、Webinar
Related: Meeting customization policies
Microsoft Purview Data Loss Prevention (DLP)
Prevents sensitive information from leaking outside the org by applying DLP policies to Exchange Online/SharePoint Online/OneDrive/Teams to block sharing/sending and warn via policy tips. Distinct from labels (classify) and retention (preserve).
Prerequisites: Microsoft Purview、Microsoft Teams、OneDrive、Retention policy
Meeting policies
Control meeting features (recording, transcription, lobby, screen sharing, participant permissions) per user. Distinct from meeting templates (blueprints) and meeting customization policies (appearance).
Prerequisites: Meeting templates
Related: Meeting customization policies
Guest access
Invites external users into Teams or SharePoint to collaborate, handling external identities via B2B collaboration (Entra External ID).
Prerequisites: Microsoft Teams、SharePoint
OneDrive
Personal cloud file storage and sync—keep your own files and share as needed (SharePoint is for org sharing).
Prerequisites: SharePoint
Alert rules
A mechanism configured under Notifications & alerts > Rules in the Teams admin center that monitors device/resource health. Its main example, the Device state rule, notifies admins when the state of Teams Rooms devices, SBCs (Session Border Controllers), etc. changes to Unhealthy. It does not notify on usage-volume metrics like active user counts crossing a threshold; unlike usage reports (which you actively check), this is a passive notification mechanism focused specifically on device/equipment health.
Prerequisites: Teams admin center、Microsoft Teams、Microsoft Teams Rooms
Related: Teams usage reports
Appointments with Microsoft Teams
Teams' Virtual Appointments feature, integrated with Bookings. Customers or visitors reserve a time slot in advance and then meet with a staff member via video at that time. It's not limited to one-on-one—it also supports group appointments, SMS notifications, a virtual lobby, and a queue view for staff to manage upcoming/waiting appointments—and it's used to replace in-person visits or counter service with virtual meetings (e.g., bank consultations, retail appointment scheduling).
Prerequisites: Microsoft Teams
Communication Compliance
Microsoft Purview Communication Compliance detects inappropriate language or policy violations in email and chat and flags them as policy violations.
Prerequisites: Microsoft Purview
Join meeting issues
Failures where sign-in succeeds but a user cannot join a meeting, or features (audio, video, screen share, etc.) fail after joining. Root causes lie in the meeting/client layer—lobby wait settings, meeting policies, or network/client issues. Diagnosed via CQD or Teams client logs.
Prerequisites: Microsoft Teams、Meeting policies
B2B direct connect
A connection model that enables collaboration through shared channels without inviting external-tenant users as guests—instead, both tenants mutually trust each other via Cross-tenant access settings. The partner signs in with their own tenant identity, and no guest user object is created, distinguishing it from B2B collaboration.
Prerequisites: Cross-tenant access settings
Related: Shared channels (Teams Connect)
Channel types (standard / private / shared)
Standard for all team members; private for a limited subset with its own SharePoint site; shared with other teams/external orgs (no team join).
Prerequisites: Microsoft Teams、SharePoint
Configuration profiles
Apply common settings (language, time zone, display) to many Teams devices at once. Distinct from device tags (grouping by location/purpose).
Prerequisites: Microsoft Teams
Related: Device tags
Expiration policy
Auto-expires unused Microsoft 365 groups (teams) after a period to clean up. Distinct from a naming policy (which enforces naming).

Lets users chat/call with external domains in Teams; they do not become members of your teams. Distinct from guest access (which makes a guest a member).
Prerequisites: Microsoft Teams、Guest access
Number provisioning (Calling Plan / Operator Connect / Direct Routing)
Ways to obtain Teams Phone numbers: Calling Plan (Microsoft provides numbers and PSTN), Operator Connect (via a certified operator), and Direct Routing (own SBC to an existing carrier).
Prerequisites: Microsoft Teams
Related: Teams Phone
Policy assignment
Assigning Teams policies to users or groups (group assignment auto-rolls out). Distinct from a policy package (a predefined bundle).
Prerequisites: Microsoft Teams
Related: Policy packages

Predefined bundles of multiple Teams policies tailored to a role (education, healthcare), applied together. Distinct from policy assignment (applying to users/groups).
Prerequisites: Microsoft Teams
Related: Policy assignment
Resource account
An account required to assign a phone number to an auto attendant or call queue. Distinct from a regular user number.
Related: Auto attendant、Call queue
Microsoft Teams Rooms
Dedicated Teams devices for meeting rooms; configure a resource mailbox account and the system, and manage firmware.
Prerequisites: Microsoft Teams
Town hall
A large-scale, one-way broadcast event format for internal audiences, aimed at delivering information from presenters (e.g., all-hands meetings, executive announcements) rather than attendee interaction. It scales larger than a webinar (up to tens of thousands), with only a limited Q&A feature optionally enabled.
Prerequisites: Webinar
Related: Appointments with Microsoft Teams
Teams usage reports
A set of aggregated usage reports available in the Teams admin center, visualizing Teams usage, user activity, device usage, app usage, and PSTN usage, among others. It reports on a different axis (volume/usage) than CQD (Call Quality Dashboard), which analyzes call/meeting audio quality trends.
Prerequisites: Teams admin center、Microsoft Teams
Related: Alert rules、Call Quality Dashboard (CQD)
Webinar
An online event format that collects attendee information via a registration form and tracks attendance. It is presenter-centric—attendees are primarily viewers, with only limited interaction available through Q&A and chat—which distinguishes it from a regular Teams meeting where all participants have symmetric rights. Post-event reports on registrants/attendees are available. Scales up to roughly a few thousand attendees; suited to marketing or training scenarios that are presentation-driven and need attendance tracking.
Prerequisites: Microsoft Teams
Related: Appointments with Microsoft Teams
Microsoft 365 Copilot
An AI assistant embedded in apps like Word, Excel, Outlook, and Teams. It operates only within data the user can already access and creates no new access. Requires a separate license.
Prerequisites: Microsoft Teams
Conditional Access
Grants or challenges access based on conditions like location, device, or risk (a Zero Trust implementation).
Advisor for Teams
A deployment aid to plan large org-wide Teams rollouts and check readiness/recommendations.
Prerequisites: Microsoft Teams
Calling policies
A policy that controls which calling features a user can use—permitting or blocking outbound calling, call forwarding, delegation, call recording/transcription, etc. on a per-user or per-group basis. It is one of several voice-related policy types alongside voicemail policies and voice routing policy, collectively termed voice policies.
Related: Voicemail policies
Call Quality Dashboard (CQD)
Aggregates quality data across many calls/meetings to analyze trends and identify sites/subnets with concentrated quality problems. Distinct from Teams usage reports (which aggregate usage).
Prerequisites: Microsoft Teams
Related: Teams usage reports
Frontline teams
A configuration providing a team experience suited to shifts and routine tasks for frontline workers.
Prerequisites: Microsoft Teams
Information Barriers
A Microsoft Purview feature that proactively blocks chat, calls, file sharing, and team search/join between specific departments or groups via policy. Used to technically enforce conflict-of-interest regulations (compliance walls), such as separating research and investment banking divisions at a securities firm. Unlike Communication Compliance, which detects after the fact, this prevents the communication from occurring in the first place.
Prerequisites: Communication Compliance、Microsoft Purview
Multitenant organization (MTO)
A configuration to operate multiple tenants as one integrated organization. Different in purpose from shared channels (per-channel collaboration).
Prerequisites: Shared channels (Teams Connect)
Naming policy
Enforces prefixes/suffixes and blocked words in team/group names. Distinct from an expiration policy (which expires unused groups).
Related: Expiration policy
Teams for VDI
Configuration that optimizes Teams audio/video media in virtual desktop (VDI) environments.
Prerequisites: Microsoft Teams
Retention policy
Keeps data for the required period and deletes it when no longer needed, managing its lifecycle.
Cross-tenant access settings
Per-partner-tenant control of inbound/outbound access and whether to trust the partner’s MFA/device-compliance claims. Differs in role from cross-tenant synchronization (auto-provisioning users).
Sensitivity labels
Classify data and apply protection (encryption, usage limits); labels travel with the file, persisting outside the org.
Sign-in issues
Failures to sign in to the Teams client stemming from the identity layer—authentication, token acquisition, MFA, or Conditional Access policy evaluation. Diagnosed by checking Entra ID sign-in logs for the block reason and policy name. Distinct in root-cause layer from join meeting issues (signed in but a meeting/feature fails).
Prerequisites: Conditional Access、Join meeting issues、Microsoft Teams
Purview Information Protection
Microsoft Purview Information Protection discovers and classifies sensitive information and applies protection (encryption, access restriction, watermarks) via sensitivity labels. It is foundational to limiting exposure in Copilot responses.
Prerequisites: Sensitivity labels
Related: Microsoft Purview
Microsoft Teams Network Assessment Tool
Sends real media traffic to measure packet loss/latency/jitter, evaluating whether the network suits Teams. Distinct from Network planner (advance planning).
Prerequisites: Microsoft Teams
Related: Network planner
Network planner
A planning tool that models required bandwidth and impact in advance from sites/personas/network sites before a Teams rollout. Distinct from the Network Assessment Tool (which measures quality with real media).
Prerequisites: Microsoft Teams
Self-help diagnostics / client health
Self-help diagnostics for Teams auto-checks common issues with guidance; client health shows client version/connection state in the Teams admin center. Detailed investigation uses client-side logs; light glitches use clearing the Teams client cache.
Prerequisites: Teams admin center、Microsoft Teams
Team archive
An action that puts a Teams team into a read-only state. Channel conversations and files remain viewable but new posts and edits are blocked. An option at archive time lets you also set the associated SharePoint site to read-only, but the underlying Microsoft 365 group itself remains active—membership management, for example, is still possible. Unarchive restores it to normal. Used when a project ends and you want to preserve the record while halting activity.
Prerequisites: Microsoft Teams、SharePoint
App permission policy
Controls which apps users can use (allow/block by Microsoft/third-party/custom). Distinct from an app setup policy (pin/pre-install).
Related: App setup policy
