How one Enterprise org account reaches several workspaces: the Open, By Request, Invite Only and Hidden access settings, routing join requests, adding members and guests to another workspace, IdP-group workspaces people can't leave, Frontline limits, and removing someone from a workspace versus deactivating them.

- Certification: Salesforce Slack Administrator
- Exam section: Workspace and Org Management
- Study guide: https://www.certifyforce.com/study-guide/slack-administrator

**Official exam objective:**

> Given a scenario, determine how to manage a user account's access to multiple workspaces.

## What the exam expects

- Choose a workspace access setting (Open, By Request, Invite Only, Hidden) from visibility and joining requirements, and route By Request approvals to the right people.
- Add an existing org member, a guest or a Frontline Member to another workspace by the correct route.
- Explain why someone can't leave a workspace, and when an IdP group connection is the better way to manage workspace membership.
- Distinguish removing a person from one workspace from deactivating their account in an Enterprise org.

Key terms:
- **Workspace access**: the Workspace settings preference that decides how org members find and join a workspace.
- **Join or leave workspaces**: the member menu for browsing, joining, requesting and leaving workspaces in an Enterprise org.
- **Default workspace**: a workspace a member can't leave on their own, including any workspace they were added to through an IdP group.
- **Remove from workspace**: a workspace-level action that keeps the person's account active in the org.
