Workspaces rarely die; they go silent. A project ends, a team reshuffles, and the rooms remain — searchable, memberless in spirit, and quietly expensive to keep. Endings, handled deliberately, are the difference between an environment that stays navigable and one that merely grows.
Find the quiet rooms first
The reports you never open answer for you: last conversation, last document, last member added. A workspace is a candidate for review when silence stretches for a quarter — earlier if it has no active owners remaining.
- Expiry policies put a clock on newly created workspaces; the owner receives a prompt to renew, and the default is renewal when nobody objects. Perfect for project-shaped teams with project-shaped runs.
- Manual retirement suits the rooms that expire awkwardly — long-lived teams with a finished chapter inside them.
The habit
Archiving is not deleting. An archived workspace preserves the record — read-only — while making the channel list honest again. Deleting is the irreversible door; walk it only when data-retention requirements demand it (and note the platform’s “deleted” is not always immediate — grace periods exist precisely because someone always needs one more look).
Preserve the memory worth keeping
Before an archive, export or note the two artefacts future readers will want: the final decision record and the file inventory. Both fit in a summary post that becomes searchable the moment you pin it to the room.
Decide endings the way you decide beginnings — with rules, not opinions — and the environment keeps a shape people recognise. The fastest-growing teams are not the ones that never end anything. They are the ones who know the shape of done.
