Tenant
A tenant is the top-level Microsoft 365 container for an organization. It holds users, groups, licenses, domains, and all configured cloud services.
User account
A user account is an identity object in Microsoft 365. It stores sign-in information and can be assigned licenses, mailboxes, and permissions.

A Microsoft 365 group is a mail-enabled membership object. It provides shared mailbox, calendar, SharePoint site, and Teams resources to its members.

Admin center
An admin center is a web portal for managing Microsoft 365 settings. The Microsoft 365 admin center handles users, groups, domains, and licenses.
Guest account
A guest account is an external user identity invited into a Microsoft 365 tenant. Guests can access shared Teams, SharePoint, and files when permitted.
Sensitivity label
A sensitivity label classifies and protects content by applying encryption, markings, and sharing restrictions. Labels travel with files and are honored by Copilot.
DLP policy
A data loss prevention policy detects sensitive information and can block, warn, or audit sharing across Exchange, SharePoint, OneDrive, and Teams.
Retention policy
A retention policy applies retain or delete rules to an entire location, such as all Exchange mailboxes or all SharePoint sites.
Retention label
A retention label applies retention or deletion rules to individual items such as emails and documents. It can be applied manually or automatically.

Audit log
The unified audit log records user and administrator activity across Microsoft 365 services. Investigators search it for events and actions.

Microsoft Purview
Microsoft Purview is the compliance portal for sensitivity labels, DLP, retention, eDiscovery, audit, and insider risk across Microsoft 365.
Copilot permission inheritance
Copilot inherits the signed-in user's Microsoft 365 permissions. It can only surface content the user can already access, so oversharing becomes visible.
Oversharing
Oversharing is when site or file permissions grant broader access than intended. Copilot can then surface that content to more users.
Records management
Records management uses retention labels to declare content as records and control its retention and deletion for compliance.

Connector
A connector lets an agent access an external system or data source through a configured API or predefined integration.
Environment
A Copilot Studio environment is a container for agents, connectors, and data. Environment roles control who can build and manage agents.
Agent sharing
Agent sharing distributes an agent to users or groups. Sharing can be limited to the maker or extended across the organization.
