Extranet workgroups are for collaboration with external users like customers, partners, and suppliers. These users have partial access to your Bitrix24 account and can use tasks, feed, calendar, drive, and chat, but only with members of the same workgroup.
Extranet users in Bitrix24

Bitrix24 introduces collabs, a new way to interact with external teams and customers. The main feature of a collab is the chat, where you can discuss work issues, hold general calls, create tasks, and share files. The entire communication history is saved in the chat, and you can find any member if needed.
Collabs: Getting started

A guest is a user invited to a collab, like an external contractor or partner working on a project. Guests have access only to collab tools: chat, tasks, files, and calendar. You can invite a guest to a collab using email, phone number, link, or QR code.

An extranet user is an external user invited to an extranet workgroup. They have access to Bitrix24 tools within the workgroup, such as feed, tasks, chats, calendar, and more. You can invite an extranet user to a workgroup using email or phone number.

A collab chat is the central place in Bitrix24 for a guest.

An extranet workgroup is the central place in Bitrix24 for an extranet user.
