A Space belongs to one Account, but it can be opened to another Account through a collaboration. People reached that way are not Space members; their access comes from the collaboration and can be withdrawn without touching the Space.

## What an administrator sets

Space administration shows **Shared with collaborations**: **Members of the Accounts in these collaborations can read this Space's channels, or read and post, once collaboration access is on.** Each collaboration in the list is tagged **Read only** or **Read and post**.

One switch, **Collaboration access**, decides whether any of it takes effect: **Off keeps every grant inert; on lets the listed collaborations in.** Only a Space administrator who may edit the Space profile can move it; everybody else sees **Only Space administrators can change collaboration access.**

The collaborations themselves are not created in Spaces. If the list is empty you see **This Space is not shared with any collaboration. Account administrators share Spaces in Space administration.**

## What it looks like from the other Account

A channel reached through a collaboration appears in your navigation column with the rest. Its header carries one extra line, **Shared by {{accountName}}**, naming the Account that owns the Space. There is no other marking.

What you can do there depends on the collaboration's tag. With **Read and post** you take part normally. With **Read only** you can read, search, see who is typing, and follow threads, but a send is refused and the channel shows **This account is not authorized to send in the selected channel.**

You hold no Space administration in a Space you reach this way, so **Space settings** does not appear.

## When access disappears

Access through a collaboration ends the moment any part of the chain stops holding: the switch is turned off, the grant is revoked or expires, or your Account's place in the collaboration ends. The channel then leaves your navigation column without a message. Ask the owning Account's administrator whether the collaboration is still active.
