Shared spaces is a great tool to keep your workspace organised and structured, especially when you’re part of more than one team, have a broad variety of tasks or if you’re an admin. Also, when you regularly share your screen, like a teacher with their students, spaces are ideal to secure sensitive information (like unread emails in the email live tile). Just create a space with information that others are allowed to see.
There are different types of spaces you can create, e.g.:
Department or team-based space
A shared space can only contain shared tile groups and can only be managed by admins. A shared space is visible to a user if he or she has access to at least one shared tile group that is visible in that space. Users only see the shared tile groups in a shared space to which they have access.
